Steamroller

Steamroller is a term used by smokers of cannabis to describe a type of pipe that consists of a hollow tube with both ends open, and a bowl on one side near one end. It is presumably called this because of its resemblance to the front wheel of the piece of machinery. A steamroller is used by filling the bowl with cannabis, putting ones hand over the end of the pipe nearest the bowl, putting the other end in ones mouth, lighting and inhaling until the chamber is filled with smoke, and then removing ones hand from the end and quickly inhaling the collected smoke.

Steamrollers are more harsh on the throat than normal pipe/bong hits.
