1. Adjective: A whiny guy who thinks that he can get people to like him through self flagellation about his white privlidge and through threatening to take away fundamental human rights cause he says it's for the good of society. No one actually likes the Beto male and this is very frustrating to him, considering his entire persona is based on doing and saying what he thinks other people around him will like. Everyone sees through it though and thinks he's annoying and clueless. This leads the Beto male to lash out in explitives filled rants of frustration.

2. Someone who has never won an election. Would lose in a fight too.

Literally everyone, ever. Including the writer of this definition.

Ironic use, or reappropriation of the right-wing slur "beta male", by fans and followers of Texan Democratic politician and post-punk Beto O'Rourke.
