Jordhugger means in slang: It is also known by the names “Earth Bong” and “Earth Pipe”. This pipe is created from two ground-connected wholes. You can place small stones on one side to filter the smoke and one side is for your mouth. The other half is for you to use as a bong. Next, place your marijuana on one side of the stone and then light up. You are basically using the earth for your bong. (in Slang Dictionary, added by Adalberto Muñoz)
