British slang for messing about, wasting time, or engaging in pointless, silly behavior — sometimes used with a vague implication of inappropriate or undignified conduct. The word plays on 'tomfoolery' by swapping in 'bum' for its comedic British value. In modern usage, it mostly just means doing something daft or getting into mischief, and has shed most of the loaded connotations it once carried.

There was too much bumfoolery going on at the back of the bus for the teacher to even pretend to ignore it.
Origin: British slang; a riff on 'tomfoolery' with 'bum' substituted for comic effect; the structure follows a long tradition of bum-prefixed British humor terms. Editorial expansion authored on Slangora (model-assisted, hedged).
