A young woman reported that she was raped in a frat house bathroom at the University of Chicago — as braying bros cheered “when’s my turn” and “let me in,” outside.

The shocking report at another elite university fraternity house comes weeks after the “Cornell 7” gang rape allegations.

The alleged assault at UChicago took place early during a rowdy party at the Alpha Epsilon Pi fraternity, The New York Times reported.

The woman was not a student of the university but attended the party alongside her pal Mia Lara, 21, and another friend after seeing it advertised on the frat’s Instagram.

Lara said she and her pals were dancing in the basement and her friend started kissing a man before disappearing.

After searching the house, Lara found a small group of men cheering outside a locked door in the bathroom, “saying this like, ‘When’s it my turn?’ and ‘I want to go in there’” she told the Times.

Lara managed to force herself into the bathroom where she found her friend sitting on the floor, slumped against the wall undressed with her underwear pulled down, the outlet reported.

The man, who was also not a student at the university, had his hands on her wrists and she yelled “Make it stop” and “Get me out of here,” Lara told the publication.

Lara chased down the man outside of the frat house, accusing him of assaulting her friend, to which he allegedly responded, “She wanted to.”

The university said Tuesday it had identified a “person of interest” in the assault who has since been banned from campus, but the Chicago police has not said if an arrest has been made yet.
