another name for a GRAVITY BONG. derives from the letters G and B coming together ala DJ Tanner being called 'Deej' on the show Full House. involves a plastic bottle (the bottom inch or two cut off) with a bowlpiece implanted in the bottle top, and a bucket of water. shit fucks you up son!!!
God, I took mad beer bongs and a few lines tonight, the only shit that got me straight was that geeb son!!
