Lil B is pissed because he thinks Harden keeps jacking his "cooking dance" when he celebrates draining a big shot. Harden has been doing it all season, but Lil B says he's watching the Western Conference Finals -- and if Harden does it again ... it's gonna be curses.
Lil B tells TMZ Sports, "If Harden doesn't tell what he is doing, which is the Lil B cooking dance, he will be cursed. He needs to stop stealing Lil B swag without showing love."
Lil B is a reasonable man -- he's giving Harden until Game 3 to give him credit, but after that he says the curse goes into effect.
Not a believer? Remember, Lil B cursed Kevin Durant earlier this year, and uhh ...he's somewhere chillin' on a couch right now.
Stir at your own risk, Harden.
