What does arsey mean?
Arsey is an informal British English adjective used chiefly to describe someone who is irritable, bad-tempered, or argumentative — the sort of person who snaps at questions or makes simple requests unnecessarily difficult. Saying that someone has been 'a bit arsey today' conveys mild exasperation rather than serious condemnation, which keeps the word firmly in casual conversation rather than formal writing. A second, distinctly British slang sense describes someone who is undeservedly lucky, comparable to 'jammy': the colleague who misses every deadline yet still lands the promotion might be called arsey, usually with a hint of envious humour. The word derives simply from 'arse', the British vulgar term for the buttocks, combined with the adjectival suffix '-y'. Because it contains mild profanity at its root, it sits comfortably among friends but should be handled with care around strangers, children, or professional settings. Its vividness and brevity make it a useful shorthand for everyday friction.
Bad-tempered, irritable, or argumentative; inclined to make difficulties.
"The referee was getting increasingly arsey as the players questioned his decisions."
(British slang) Undeservedly lucky or fortunate; having success through chance rather than merit.
"She'd never studied for the exam, but she passed anyway — typical of her arsey streak."
This sense is specifically British slang and often carries playful envy rather than real criticism.
In Britain, calling someone 'arsey' can be an insult about their temper — or a backhanded compliment about how infuriatingly lucky they are.

Etymology of arsey
Arsey is a straightforward formation from 'arse', the standard British vulgar term for the buttocks, itself descending from the Old English word 'ærs', which shares distant Germanic roots with the American English equivalent 'ass'. The suffix '-y' was added in the usual way to turn a noun into an adjective describing temperament, much as 'touchy' or 'grumpy' were formed. The word developed within colloquial British speech, with the 'irritable' sense well established by the twentieth century; the later slang sense meaning 'lucky' appears to have arisen within the same informal register. It remains primarily a British and Commonwealth term, with little currency in North America.
