A Ruben
He acts like he's smart at first, but once you know him, he'll haunt you with his knowledge and his sleep schedule. Don't mess with his jokes or he'll ignore you for a week.
He was all 'I don't know anything,' then he explained the universe and I didn't sleep for three days.
I made a joke about his sleep, and he hasn't spoken to me since.
He loves his friends, especially the girls, and if you even think they're dating, he'll give you the evil eye.
