Horch

A verb for when you want to make sure there is no more green in the bowl of your pipe or bong. You hold the flame directly on the bowl and leave it there for the entirety of the hit. Typically is done after it’s already declared cashed.

The hit after the last hit.
When you can’t torch it anymore.
