The Daily Swarm was at the premiere.
Quoth Swarmer David Prince:
In the film, Kanye plays himself drunk at a club acting belligerent and boastful, telling starstruck club-goers that the song playing in the club is his. He wanders into a side room where he encounters a beautiful woman. They start having sex and then he passes out on her leopard print dress. When he comes to, he finds himself in the VIP room with his pants down – he was hallucinating and fucking the pillow. The realization startles him and he rushes to the bathroom where he vomits what look like rose petals.
Then it gets weird.
