as best as I can understand:
He got put on blast on social media by a chick saying he was bad in bed.
he got with a chick Keisha who said she like big dick niggas. ("she said she like big cocky man, so- you know, we gon' try it out")
he was balls deep in her, thought he was killing it..
she pushed him off, and he was like wtf, you ok? am I hitting it too hard?
She told him nah nigga, go deeper...
he was like deeper? I done ran outta dick! (me run outta cocky ! )
where I'ma get more dick from? (where me get more cocky from!)
Then he called her wicked and said fuck her and her deep hole.
It also sounded something like "where niggas stick their dick" but I couldn't really understand anything else to give it context.
Fake or not, this shit is hilarious and needs subtitles like a motherfucker
