Someone who is inferior in some intangible way. Maybe they don't understand anything you say, maybe they don't know what sigma males are. Maybe they're Salek. But they're clearly a beta.
Any person who unofficially comes out by directing someone else to say they "used to get lost in the closet" is such a gigantic faggot that they embody the term Beta Male.
A male who is basically a simp who lacks dominance and intelligence and is fooled and taken advantage by women who ain’t shit that only uses them for money and other things then throws them aside when there all dried up for another man
Beta-Male is the type of person to confront and catch his girl cheating on him in his own house only to get beat up by that man and get kicked out of his own house or to let his crush and her boyfriend use his Netflix or car
