To smoke with a single inhalation, a portion of marijuana through a bong, thereby ashing and emptying the entire contents of the bowl in the process.
Man, I could really go for a nice bong snap right about now.

Snapping a bong is the act of clearing the bong's bowl of cashed or spent "herb" by sucking the ash down the stem into the bong water, thus preparing the bowl to be repacked.
