bup-bup

it means shut the *$#@ Up! or it can also mean your done talking or that your talking privileges have been revoked for the remainder of the day.

Some one is saying something stupid or they are about to say something they shouldn't so you cut them off and say "bup-bup"

Rub Bup Bup interprets everything. It can be a noun, an pronoun and shit like that. It is only used by curry_king. It's used to insult, and especially annoy people. The word was made up during an english period, when a bird was making the noise RUB BUP BUP the entire week during its mating period. Curry_King responded the bird, RUB BUP BUP and the bird responded back.
