A Cornell fraternity was put on a two-year probation after members were busted in a disturbing sex competition they dubbed the “pig roast,” the university said.

The sickening game involved the Zeta Beta Tau chapter members racking up points through sexual conquests at the Ivy League campus — all by factoring in the weight of the women they slept with, The Ithaca Voice reported.

School officials said they launched a probe into the frat after receiving “multiple reports” last year regarding the cruel game.

“An investigation that concluded in January of 2018 determined that the chapter conducted a contest in which new members could accumulate ‘points’ by engaging in sexual intercourse with women,” the university said in a statement.

Fraternity pledges were reportedly forbidden from telling the women about the contest. If there was a tie, the win would go to the member who had sex with the heaviest female, school officials said.

As a result of the investigation, the frat will be required to partake in at least two events during the school’s Sexual Assault Awareness Week.

They also must hire a live-in adviser for the remainder of the probation period, subject themselves to external reviews and participate in “ongoing education on sexual violence,” the university said.

In a statement released Saturday, the Cornell chapter of the fraternity said it was in “disbelief” over the allegations of misconduct.

“The allegations described are contrary to the values that Zeta Beta Tau Fraternity espouses and works in direct conflict with the beliefs and mission of the Kappa Chapter,” the statement said.

“Our chapter has worked closely with the Zeta Beta Tau International Headquarters to draft and execute an action plan that addresses this alleged behavior.”
