Rebong
The filtered and dried powder-like residue of well-used bong water, which is then smoked due to the still significant THC content.
We were so broke that we resorted to our stash of rebong. The taste was horrible but it did get us completely stoned.
Rebong
While taking a beer bong, you throw up into the hose, but continue to finish the rest of your beer and your vomit...
Boston is such a pussy he rebonged his first one of the night.
