look up any word, like cunt:
A curse word coined by Bob and originating in Jamaica. It is really two curse words joined together to form one.

'Bumbo!' expresses one's outrage and utter shock and disbelief at the occurrence.
'Fuck' expresses the end of one's involvement in the occurrence, i.e. it expresses finality.
