Facebook CEO's Secret Frat Name Has Been RevealedS

"Slayer" was Zuckerberg's freshman frat name, his dorm-mate Rebecca Davis O'Brien writes in a Daily Beast profile of the Facebook CEO. If that makes geeky Zuckerberg sound rather unbelievably like a ladykiller, consider it might well have been a reference to his frat duties: As exchequer, Zuckerberg was responsible for collecting dues.
