When your girl says she's bored of normal sex and asks you to put it in her butt, then proceeds to scream and bawl her eyes out when it enters her butt.
Person 1: Dude, is your GF ok? She hasn't talked to you in a few days
Person: Yeah she's ok, she thought she was ready for a Dirty Cintya and turns out it was too much for her.
Dirty cinta is when you put a straw in your man’s ass and suck the shit he talks out so you don’t have to hear it anymore.… all while he makes you dinner and calls you mummy
Bro you should have seen it… she come home and put me in my place with a dirty cinta..note to self. don’t fuck her off again.
