""Careca" which means bald due to his constant shaven head. He is also called "Mata-Cobra" which literally translates to snake killer. This is a name often associated with people that cannot strike (punch) well and throw awkward "haymakers" (like if one grabbed a snake by the tail and whipped it's head on the floor). The name was a wind-up a joke amongst his training partners when Keith started training in boxing. Keith has since competed successfully in a number of boxing and kickboxing tournaments."
