Sometimes no really does mean no.

Yale's prestigious Delta Kappa Epsilon fraternity, which counts both former President George H.W. "Poppy" Bush and his son George W. Bush among its alumni, is learning this the hard way.

The frat, which has come under scrutiny before for its questionable, sexist pledging traditions, is officially suspended from recruiting and campus activities for five years, the Associated Press reported.

In the controversial video making the rounds online, pledges of the fraternity are heard chanting "No means yes, yes means anal" over and over again. The pledges were also reportedly carrying a sign that read "We love Yale sluts."

The university, which put DKE's ban in place to ensure "an educational environment free from harassment and intimidation," said it is also disciplining individual members of the chapter in addition to barring the fraternity's campus activity.

DKE originally came under fire after a YouTube video of a group of pledges singing crass songs about necrophilia and sex acts circled the web last fall.

At the time, Doug Lanpher, executive director of the international DKE office, said the offices were dealing with the chapter's actions internally, and that they "don't advocate what they said. We believe that the chapter's behavior has changed."

DKE President Jordan Forney also apologized for his fraternity brothers' behavior at the time.

"It was a serious lapse in judgement by the fraternity and in very poor taste," Forney told the Yale Daily News, calling the chants "inappropriate, disrespectful, and very hurtful to others."

The controversial rituals come amid reports that the Ivy League university is under investigation as a "sexually hostile environment" that fails to respond to sexual harassment concerns.

Alexandra Brodsky, who was one of the students who filed a formal complaint against the fraternity, said she was "glad to see that Yale recognized the gravity of the situation" and that the "disciplinary action and public discussion mark a departure from Yale's previous approach to sexual misconduct."
