A crack addict. This is because crack cocaine is a freebase form of cocaine hydrochloride.

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.

Maesean. Caleb. Willie. Basically the whole track team.

The amount of base headed-ness depends on the amount of dumb things a person does in one day. Levels ranging from being a base head to being a based god. Base god being the highest level of being based. Rodrick sykes and johnna (last name) are current holders of the based god title.
Mark and Caleb: lets go to the beach or something

Johnna: what banquet?
Mark: oh gosh you a base head
Caleb: other hand sykes
