Did You Know Vin Diesel Used To Be A Rapper? [Audio]

Well Fast 5 is still rocking at the box office so this seems relevant.  This audio is from 1986 performed by rapper Mark Sinclair, better known today as Vin Diesel.  

I can't really understand what he's rapping about.  But I sure the hell am glad he stopped and started acting!  Cause wow that sucked out loud!
