Why these three sources matter
Every variety of English borrows images from its own daily life. American English leans on baseball and American football. British English leans on cricket, on the fine social distinctions of an old class system, and on tea, which turns up in more idioms than any other drink.
An American reader knows all the words in "a sticky wicket." What is missing is the picture: a cricket pitch after rain. Supply that picture and the idiom explains itself. So this page teaches the reference first and the phrase second.
Cricket in 150 words, for the American reader
Cricket is a bat-and-ball game with some family resemblance to baseball. A bowler delivers the ball to a batsman (now often called a batter) who defends a wicket, a set of three wooden stumps with two small crosspieces on top. Confusingly, "wicket" also names the strip of ground between the two sets of stumps, which is also called the pitch.
The batsman scores runs by running between the wickets, or by hitting the ball to the edge of the field: four runs if it rolls over the boundary, six if it clears the boundary without touching the ground. A bowler who gets a batsman out is said to take a wicket.
Cricket is played outdoors, and rain changes the ground. That is all you need for the next section.
Cricket: the biggest source of British idioms Americans don't understand
A sticky wicket
A difficult or awkward situation. The Phrase Finder's entry on "a sticky wicket," which we read on September 27, 2026, explains that the wicket here is the playing surface, and the phrase alludes to how hard it is to bat on a pitch made wet and treacherous by rain. It quotes Bell's Life in London in 1882, describing Australians who "found themselves on a sticky wicket," and gives the first figurative use as The Gleaner of Jamaica in 1930: "I am batting on rather a sticky wicket." It also notes the phrase became common in cricket-playing Commonwealth countries before spreading further.
Many Americans have heard it, often in films, but it can sound a little old-fashioned even in Britain. "A tough spot" is the plain US version.
Knocked for six (or hit for six)
To be badly shaken, surprised or set back: "the news knocked me for six." A six is cricket's biggest single hit. The Phrase Finder's entry on "hit for six" quotes Bell's Life in London in 1847 ("Sewell then made a brilliant hit for six"), gives the first use as a verb in the Naval and Military Gazette in 1866, and dates the first figurative use to the Times Literary Supplement in 1937. Note the direction: in cricket it is the bowler who gets "hit for six," so the figurative victim is the one on the receiving end.
The closest American phrase is "knocked for a loop."
Not cricket
Unfair or unsporting. Wiktionary defines it as "unsportsmanlike" and tags it idiomatic and humorous. The phrase rests on cricket's long reputation as the game of gentlemanly fair play, which ties it to the class idioms further down. Today it is usually said with a wink.
Off your own bat
On your own initiative, without being asked: "she rewrote the report off her own bat." The Phrase Finder explains that in cricket, runs scored "off his own bat" were the ones a batsman earned with his own strokes, as opposed to extras the other side gave away. It quotes a 1742 score record collected in Henry Thomas Waghorn's Cricket Scores and gives the first figurative use to the Rev. Sydney Smith in 1845.
Hat trick
Three successes in a row. This is the cricket idiom Americans already know, through ice hockey and soccer. The Phrase Finder quotes James Lillywhite's Cricketers' Annual of 1877 describing a bowler "performing the hat-trick" and reports the theory that a bowler who took three wickets with successive balls was given a new hat. It presents that as a theory, not a documented fact, and so do we.
Class: posh, common and the done thing
Posh
Upper class, or smart and expensive: "a posh hotel," "a posh accent." Wiktionary adds that in Ireland, Scotland and the north of England it can carry a sting, meaning stuck-up.
The famous story says "posh" stands for "port out, starboard home," the shady side of a ship on the voyage between Britain and India. Wiktionary calls this a popular folk etymology with no evidence behind it. Its preferred theory is the Romani word posh, "half," which may have led to a slang word for money. The honest summary: origin uncertain, and the ship story is almost certainly wrong.
The done thing, and "common"
"The done thing" is behavior that social custom expects: "it's not the done thing to leave before the speeches." Wiktionary labels it chiefly UK. Its quotation from a 1985 novel shows how closely it ties to class: "I wanted to be called Linda but Aunt Angela said that was a common name… not the done thing."
That quotation holds a second trap. In British English, "common" can mean vulgar or lower class, so calling something common is an insult that an American reader will easily miss. Manners idioms like these have a long history in Britain; see what the references say about mind your Ps and Qs, which has five theories and no winner.
Bob's your uncle
"And there you are, job done," said at the end of a set of instructions. The Phrase Finder's entry on "Bob's your uncle," read on September 27, 2026, reports the popular story: Prime Minister Lord Salisbury appointed his nephew Arthur Balfour to office in the 1880s, so anyone with "Bob" as an uncle had an easy path. It rejects that story for lack of evidence, since the phrase is not documented until decades later. Its earliest citation is The Stage of London in January 1923, followed by a Dundee revue titled "Bob's Your Uncle" in 1924, which points to music hall. Origin: not settled.
Tea: teacups and personal taste
Storm in a teacup
A big fuss about something trivial. Wiktionary labels it UK and gives the American form as "tempest in a teapot," which its usage notes call by far the most common form in the US. Wiktionary dates "tempest in a teapot" to 1838. This is the easiest British idiom to translate, because the American version uses almost the same picture.
Not my cup of tea
Not to my taste: "opera isn't really my cup of tea." Wiktionary defines the idiomatic "cup of tea" as an activity or domain someone is interested in, "one's personal preference." Americans understand it and use it; it is on this list because British speakers reach for it far more often, and use it as a polite way to say they dislike something. Note that in Britain it is gentle, not dismissive.
A related word: a "cuppa," which Wiktionary lists as the colloquial name for a cup of tea itself.
Everyday British idioms Americans trip over
Taking the mickey
Mocking or teasing someone: "are you taking the mickey?" Wiktionary labels it UK, Irish and Commonwealth slang, and says the origin is uncertain, possibly Cockney rhyming slang. Americans would say "pulling my leg" or "making fun of me." It is casual, and fine among friends.
Sod's law
The principle that whatever can go wrong will go wrong, usually with a touch of irony. Wiktionary gives the example "It's Sod's law that it will rain when going for a picnic" and lists Murphy's law as a synonym. Be careful with register: "sod" is a mild British swear word, so Sod's law is fine in the pub and out of place in a formal email.
Using British idioms with an American or international audience
- In a business email to US colleagues: swap "a sticky wicket" for "a tough spot" and "off my own bat" for "on my own initiative." The meaning survives; the confusion does not.
- In speech: "Bob's your uncle" and "not my cup of tea" usually land fine, because the tone carries them. Cricket idioms often do not.
- For ESL readers: cricket idioms are especially hard, because even British learners of English may not follow the game. Add the plain meaning in the same sentence.
- Watch the rude ones: "taking the mickey" and "Sod's law" are casual, and "sod" is a mild swear word. Keep them out of formal writing.
The pattern runs both ways. Americans baffle British listeners with baseball idioms for exactly the same reason. And for how a reference decides that a date like 1882 counts while a good story does not, see how a phrase origin is traced.
Frequently asked questions
What does "sticky wicket" mean?
A difficult situation. The Phrase Finder explains it comes from cricket, where batting on a pitch softened by rain is hard, and gives the first figurative use as 1930.
Is "posh" really short for "port out, starboard home"?
No. Wiktionary calls that a popular folk etymology with no evidence. The origin is uncertain, with a Romani word meaning "half" as the leading theory.
What is the American version of "storm in a teacup"?
"Tempest in a teapot," which Wiktionary describes as the most common form in the US.
Where does "Bob's your uncle" come from?
Nobody knows for certain. The Phrase Finder rejects the popular story about Lord Salisbury and his nephew Arthur Balfour and finds the phrase first in 1923, in the London theater paper The Stage.
Is "taking the mickey" rude?
It is casual slang, not a swear word. It means teasing or mocking someone, and it is fine among friends but too informal for business writing.
