Mateo is a socially akward and wants lots of attention while non of his friends give to him so he starts to run around the school halls acting like a monkey

A boy that isn’t the smartest but still thinks he is. Thinks he’s good at sports but unfortunately he’s not. He is most likely gay and is proud of it.

Hilarious guy with perfect hair. He is the type of guy who always has your back! He’s kinda shy at first but has a big heart. He’s the type of guy to play clash of clans but give up at town hall 11 because he’s bored.

Mind reader, Mateo

A very moronic friend who can be reliable at all times, if you ever meet a Mateo, you must cherish them and take care of them as they are normally autistic and can't do anything for themselves
"Fuck Mateo."
