Rap Legend Bun B -- Lil B's Harden Curse Is Bogus ... 'Cooking Dance' Started In Texas

This is gonna get interesting ...

Texas Rap legend Bun B is turning the tables on Lil B ... saying his "Based God Curse" can't hurt the Houston Rockets ... cause LB is as guilty of dance jacking as James Harden.

Lil B recently took credit for Houston coach Kevin McHale losing his job ... saying as long as the franchise enables James Harden to steal his "Cooking Dance" ... they'll remain cursed.

TMZ Sports spoke with Bun B ... and he tells us the Rockets are immune to the so-called curse cause Lil B TOTALLY JACKED the dance from another rap god, Pimp C.

"I've known Lil B since he was in the Pack. I support him musically. But we don't buy into that because we know that Pimp C created [the cooking dance] not Lil B. We don't stand for that."

That wasn't the only curse Bun B was willing to tackle ... he also dispelled any notion that there was a Kardashian curse plaguing the Rockets ... because Harden is dating Khloe.
