Despite holding an office party with Twitter-branded beer pong tables and a sign in Greek- style lettering that read “Twitter Frat House,” Twitter's male-dominated culture is nothing like that of an American college fraternity, says Twitter.

A photo of the "Twitter Frat Party" surfaced (on Twitter) last night, posted by a female employee of the company. Though she quickly deleted it, the Global Women in Tech Facebook group had already posted the image, which has circulated widely.

A spokesperson for Twitter, Jim Prosser, confirmed to Fusion that the company-funded frat party did take place, reportedly held for the alpha bros of the revenue team (naturally). But Prosser cleared up any confusion about whether or not Twitter was an actual fraternity, issuing a standard Silicon Valley apology.

“This social event organized by one team was in poor taste at best, and not reflective of the culture we are building here at Twitter,” Prosser said. “We’ve had discussions internally with the organizing team, and they recognize that this theme was ill-chosen.”

There it is. Twitter is not a fraternity. It's just a male-centric environment where dudes can play beer pong, do kegstands, and get in gender discrimination lawsuits.

As the New York Times reports, Twitter faces a lawsuit seeking class-action status that was filed by a former engineer, Tina Huang. Huang alleges that the process for promotion at Twitter is not clear, and is biased in favor of male employees.

Twitter has emphatically asserted that it is a "a diverse and supportive" place. So, for that matter, are fraternities — they just don't accept women.
