On Wednesday (Mar. 7) Michael Rapaport hopped on Instagram to air out Lil Xan over his comments dismissing Tupac as boring. The 47-year-old hip-hop purist, a rant was in order as soon as he got a load of the reason he rated Pac's music a dismal '2' during a recently released interview with Revolt. And he definitely minced no words.

"Little buck tooth rabbit face motherf*****r. You need to apologize, alright? And you don't need to apologize to Tupac or Tupac's fans. You need to apologize to whoever the f*** raised you, or didn't raise you - for raising you to be a dumb f***," Rapaport said in a video that drew support from many of his 1 million followers. "You don't get to speak on anything that has to do with hip hop or rap music, alright?"

For Rapaport, hearing anything that might carry a hint of disrespect towards the late prophetic rapper is beyond blasphemous. He takes it personally.

Many who are up on the roots of the actor/comedian's love for the genre may recall his unique experience of having been present the very day Pac met Snoop Dogg at a wrap party for Poetic Justice. The way Rapaport tells it, the only reason he even auditioned to be in the film was for the opportunity to meet the rap legend.
