A guy that everyone thinks is the most innocent of the group but is really the most sexual one and gets all the girls. Despite his sexual drive he has a tiny penis, often ranging from 1 - 2 inches. He would usually have a girlfriend (with a name like Eve) who he would send incredibly large text messages to. His friends would mock him for it by saying they look like essays.
Oh look at that innocent guy, he's such an Andres.
Me: Who's that guy hanging out with all the girls?
Friend: Oh, that's Andres, he's with his friends from choir.
