A big, obnoxious dude who always says what's on his mind. He might be a jerk, but you can count on him to always give you the honest truth. He thinks he's a lot cooler than he actually is, but people are friends with him anyway because they think he's funny.
Dude.. who is that douche over there?

Oh, that's just Louis, man. You get used to him.

is an awesome guy who always has a smile on his face. He is a very good friend and an awesome lover. He is very understanding and he always pushes you to do your best because he knows you are more capable than what you think. He is very kind and generous. He is sweet and cute. He works hard and does the impossible.
