'Alpha King' Nima Yamini Changes Matt Rife Oral Sex Story, Says It's Satire

The self-described comedian who accused Matt Rife of performing oral sex to get ahead in Hollywood is walking back his salacious claim -- Nima Yamini says he was just joking.

In a video posted Friday, Nima says he was just doing a parody bit when he alleged Matt performed fellatio on a couple of Hollywood execs who promised fame in exchange.

TMZ broke the story ... Matt's considering legal action over the claim, and, interestingly, Nima didn't clarify the whole casting couch tale until after we posted about Matt's intentions.

However, Nima says that's not why he's walking it back ... instead, he says he's pissed at a conspiracy-pushing social media account that reposted his original video -- without his permission -- and made it seem like a serious allegation.

He insists that was never his intention.

Nima says the whole thing was meant as satire, and he doesn't know Matt personally and has never met him -- let alone ever being in the same room as him with Hollywood honchos.

What's more, Nima says the "joke" should not discredit Matt or how hard he's worked to become a famous comedian.

With Nima doing some serious backpedaling here, it will be interesting to see if Matt follows through with his legal threats.
