What is a gravity bong?

A gravity bong, also known as a GB, geebie, bucket bong, grav, geeb, yoin, jib, buckie or ghetto bong, is a method of consuming smokable substances such as tobacco, or possibly cannabis (if it is legal in your area). The term describes both a bucket bong and a waterfall bong, since both use air pressure and water to draw smoke.
