drop a bomb

(slang, vulgar) To break wind, to fart.

Crude Australian and British slang meaning to fart, pass gas, or break wind. The phrase is about as delicate as the act itself — which is to say, not at all. It's the kind of direct, no-nonsense expression that thrives in informal settings, especially among mates who've long stopped pretending bodily functions don't exist. Widely used in casual conversation, comedy, and anywhere adults decide to abandon decorum.

(euphemistic, idiomatic, slang, vulgar) To defecate.

(British, idiomatic, intransitive, vulgar, _, slang) To make a mistake.
