the clump of stuff at the bottom of a (tobacco?) pipe bowl, after it has been smoked.

The unspent ash of tobacco or marijuana that accumulates at the bottom of a pipe (usually the inside of a bong)which can be smoked.
If there is no weed around, you could clean the inside of your bong and smoke the dottle out of it.
