Twitter hosts 'frat party' while fighting gender discrimination lawsuit

Theme of kegs, red Solo cups and beer pong provokes outrage from equality campaigners - and an apology from Twitter

Twitter has apologised for hosting a frat house-themed party for its staff while the company is in the middle of a class-action lawsuit for gender discrimination.

The party was held on Tuesday by one of Twitter's San Francisco-based teams for their internal "happy hour", and involved frat-style accoutrements such as a keg, red Solo cups, and beer pong, all under faux-Greek letters reading "TWITTIR IRIT HIVSI".
