Freddie Gibbs & Matt Barnes Roast Man Whose Mom Dated Tupac

Freddie Gibbs' love for Tupac quickly turned into jokes during a recent visit to the popular basketball podcast "All The Smoke" ... after Matt Barnes outed a crew member whose mother once dated the late rap icon.

The crew member gave himself away off-screen by putting his head down when Matt dropped the bombshell ... derailing the convo with merciless jokes.

Freddie and Matt immediately launched on the guy ... with Freddie quipping the opening lyrics to Pac's classic sex romp "How Do U Want It" which was dedicated to the guy's mother.

Despite being in awe of Tupac and even owning up to emulating his shaved head, Freddie admitted his fandom for Pac would've shrunk if he was a teenager during such a relationship.

Stephen Jackson tried to keep the peace but Matt laid the jokes on even thicker ... claiming the poor guy had to suffer when Mr. "I Get Around" paid his house a visit. 🙈
