whilst people may think that B.B.B has multiple meanings, it really only has one. the meaning of it is Bumming Boys in the Bathroom. this is mostly used for posh private/catholic school boys. B.B.B dosent have a deeper meaning below bumming boys in the bathroom, it genuinely means that you were shoving you cock into ur friends ass.
