What does numpty mean?
Numpty is an informal noun for a person who is regarded as foolish, clumsy, or incompetent. It is especially useful when describing someone who has made an obvious or avoidable mistake: calling a colleague a numpty conveys embarrassment, rueful amusement, and gentle criticism at the same time. The word has a distinctly British flavour and is now also understood in American and other varieties of English, although it remains more common in speech than in formal writing. Its tone is usually playful or mildly derogatory rather than deeply hostile, and context determines whether it is affectionate teasing or straightforward insult. Numpty is also frequently used in the expression “a bit of a numpty,” which softens the criticism slightly. Because the term can offend, it is best reserved for informal situations in which the speaker knows the audience and the intended level of friendliness.
