Joe Biden may be out of public office, but he still killing it in his role as public advocate.

The former vice president, who has a reputation for being pretty frank, didn’t mince words with an audience of college students at George Mason University in Fairfax, Va., Wednesday night, according to the Washington Post.

“Guys, a woman who’s dead drunk cannot consent. You are raping her,” he told the audience. “Consent requires affirmative consent and if you’re too drunk to be able to consent, it’s not consent.

The speech was part of Biden’s “It’s On Us” campaign to stop sexual assault, for which he’s written op-eds, made PSAs, and even guest starred in Law & Order SVU. He received a standing ovation from the students at GMU Wednesday as he talked frankly about the issues of consent on college campuses and how to change rape culture.

“Here’s the thing, guys, you got to speak up and you got to do what my father taught me: Turn and say, ‘You’re a horse’s tail,’ but only more graphic,” he said.

The campaign builds upon Biden’s legacy as a women’s rights advocate, despite some controversy with women earlier in his career. As a senator, he helped author the initial Violence Against Women Act that is now law.

Biden urged the men at the school and beyond to quash locker room talk that went over the line. He also said that everyone — men and women — need to be able to discuss assault and consent for anything to change.

“I say to you guys, please, please act like men. Rape and sexual assault are not about sex, it’s about power. If you want to be a man, stand up, man.”

Biden had a hand in bringing down the rates of domestic violence across the country over the past 20 years, and in increasing the resources for rape centers, counselors, and a national hotline. Now, he wants to make sure college students get the message too.

“Change the culture,” he told a crowd at George Mason. “You can do it.”
