Theta male 

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
