Marliesia Ortiz broke up with Swae Lee because she claims Blac Chyna -- who happens to be known for her awful blowjobs -- gave the Rae Sremmurd rapper head.

She outed the slippery relations between Swae and Blac with the social media message “You love sucking people niggas dicks huh? @blacchyna."

Then she continued her shaming of Chyna with a video post mocking her super-sized booty.

Is that a fair representation of Chyna's bottom?

#blacchyna at the beach. Is she top 5 or top 10 right now in the game???
