well your Jamaican friends
don't read the patois dictionary.
BUMBO : bottom; backside. A common curse word, especially in combination with CLOT (cloth),

Myself, I don't ask my Jamaican friends about that stuff. They get told to fuck off out if they don't want to speak English.

*frowns*
My many many Jamaican friends have been lying to me.

(edit - I don't actually have any jamaican friends, not any more. Probably because I was always asking them what their funny words meant)
