Main-Characteritis

When someone thinks that they're always the smartest, toughest, prettiest or just the most interesting person in the room without actually being able to back it up.

"Why does Alyssa always talk so loud? It's like she wants the people next door to hear her, too."
"Just try to ignore her, she has Main-Characteritis."

Gym fag

Someone who works out solely for vanity and cares nothing about actual health, fitness, or strength.

I hate running into Trevor at the gym. He's only like 140 lbs but he's always shirtless because he wants everyone to see his abs. All he even does there is flex in the mirror like a total gym fag.
