dumbarse
Fool, British slang
Dumbarse is British and Australian slang for a stupid person, equivalent to American "dumbass." It combines dumb (stupid) with arse (the British spelling of ass), creating a vulgar but relatively mild insult.
Don't be such a dumbarse—read the instructions first.
The term is often used affectionately among friends or dismissively toward someone who has done something foolish.
