Thinks he knows everything. Sure, maybe he's studying to be an engineer, but it doesn't make up for the fact that he is a total fucking tool bag. Often resembles an uglier version of Bob Sagat but is somehow convinced he is gods gift to woman. Even his friends think he is an ass hole. Acts like a huge dick, yet his actual penis resembles a shriveled raisin. If you meet someone named Matt, it is your civil duty to kick him square in the balls. He is the asshole of society.
person1: Who's that total douche bag?
person 2: Oh, that's Matt. He's a fucking ass hole.
