Tweety Bird Loc (real name: Richard Johnson) is a rapper who's beefs with Eazy-E, and many East Coast rappers like Tim Dog often took comical levels.
Though he's a real rapper, he too, is one of those rare rappers who also plays outlandish characters.
In many of his songs he threatens Eazy-E, Tim Dog, in comical fashion. He is outright nasty though the melodic tone of his music balances the nastiness to make it more laid-back. Despite his villainous criminal tendencies, Tweety is no where near as bad as Sticky Fingaz and in fact comes off as friendly if you're on his good side.
