Compassing

[Becky]

In the subculture of marijuana slang, [compassing] is a tool used to assist a [smoker] who is using a pipe. The person who took the hit directly before the person who now has the bowl says, for example Northeast, if the green is to the top right of the bowl (farther away from [the smoker]), or Southwest, if the green is to the bottom left of the bowl (closer to the smoker).
