GB 

A device used by crackhead stoners, myself included, who do not have access to an actual bong. Using a socket and a bottle with holes burned through it, you pull the smoke in using the gravity of the water falling.

Acronym for the phrase "Good Bull", which is shorter for the phrase "Good Bullshit"... because bullshit is always party-like.

"and good bull, good bull, gb, gb GB!"
