In terms of weed it is the process of grinding or breaking up weed and packing it in a bong-- You're expected to kill the bowl in one hit in most cases, since the weed is grinded up it burns quicker and therefore makes it possible for one person to burn an entire bowl in a single hit. This however will tear the SHIT out of your lungs but will get you fuckin zooted!

Guy#2: "Yeah but he's only selling shake"
Guy#1: "Its chill bro we'll just pack some snaps" :)
