Barack Obama: Yo Trav, how much grass we got left after this blunt?
Trav: None bro, let's do some roof hits to conserve.
Barack Obama: Fa'sho!

The process of smoking marijuana by heating up the tips of butter knives til theyre extremely hot, taking pieces of bud and pressing them between the tips of the flaming hot knives and sucking the created smoke through a funnel of some sort. Quite effect and a very nice clean burn.
