Slick's Mind

A Pimp Named Slickback (voiced by Katt Williams) – A Pimp Named Slickback is a pimp who gets easily irritated when someone calls him "Slickback" for short, demanding to be addressed by his complete self-professed name: "It's like 'A Tribe Called Quest' — you say the whole thing." He first appeared in "Guess Hoe's Coming to Dinner" when Granddad began dating his prostitute, Cristal. He made a cameo appearance in "Return of the King", but had no speaking lines.

He appears in the season 2 episode "Tom, Sarah and Usher," in the episode where Tom believes Sarah is having an affair with singer Usher, attempting to teach Tom to gain the respect of his wife through violence and intimidation. The character is modeled after Katt Williams' character of "Money Mike" in Friday After Next. He drives a purple BMW, which matches his purple suit. He appears in "The Story of Gangstalicious Part 2", where he is brought in by Granddad to talk to Riley about sex, and dissuade him from homosexuality.(via Wikipedia)
