Home to the baddest motherfuckers in the Greek system. Brothers share a bond for life and will kick your ass if you try to fuck with it. Also some of the smartest and most fun people to hang out with. Girls love 'em, guys wanna be 'em.
Guy 1: Dude, were you at the Theta Xi party last night?
Guy 2: Yeah man, JJ got drunk and fought two midgets. It was fuckin' sweet.

Similar to the sigma male, the theta male is someone that is on the very top of the social hierarchy, yet rejects it due to being extremely based. The theta male chooses to break the oppressive shackles of modern society by playing League of Legends and Genshin Impact all day, and eating nothing but Doritos and Mountain Dew, in the process being certified to be "morbiusly a beast" by every doctor they encounter.
NPC #1 (femoid): OMG I think I'm in love... I found a guy who's fat and retarded and doesn't shower and plays League of Legends all day... he's perfect 😍
NPC #2 (male): wow, he sounds cool. Must be a theta male

Local Sorority founded at Shippensburg University in 1966. The hottest, craziest, most down to earth and wildest party girls ever. If you're out with a Theta Kappa, you probably won't remember your night, but it'll be the best damn one of your life.
