base head

Not just a coke addict, to correct some people on here. A base head is someone that smokes cocaine that has been cut with something, and sold as more, then passed to someone and they will cook it down with a few more ingredients to make it into a yellowish toned rock, known as "crack rock"

Jeff if a base head, he smokes a gram of rock a night.
