look up any word, like donkey punch:
 
1.
The act of contriving a bong out of Misc. parts.
Dude 1: "No bong dude? Well it looks we could use this for a downstem, and that bottle over there... we will need some bubblegum and a lighter too... Uhh You got any weed so we can try this out?"

Dude 2 : "uhh... No, I thought you had weed..."
Dude 1: "well we are going to have to find someone with some green to test out this feat of Bongineering."
