A mairomaster is an
incel who compensates for his small package by
trolling guys with big dicks, calling himself an
alpha, and powerlifting to make up for a lack of masculinity. A mairomaster is generally very disliked by other men. Although self-sabotage is usually comical to an extent, mairomasters are unfunny, simply coming off as miserable assholes. They are notoriously horrible at receiving criticism and are very unmasculine.
You can tell he's a mairomaster by the
way he constantly tries to make
people think his dick is big. It's creepy.
