The French expression quelle mouche t'a piqué ?
reminds me of the rather vulgar English expression "what (bug) crawled
up your butt (and died)?" but the French expression is only informal.
It's basically asking what's up? why are you getting mad for no apparent
reason? In terms of register, the more accurate English translations
are expressions like "what's the matter with you?, what's gotten into
you?... |
