shotgun fiend 

This is a person that will go to extreme lengths or will alter their usual behavior in order to gain the privilege of riding "shotgun". This person will often undermine all of his or her ethics or moral values to assure the position of the passengers seat in an automobile. This person is frequently looked down upon or shunned from the group riding with him, but that does not make a difference because riding shotgun is enough to numb the pain of being disgraced by his peers.

Collin: (sprints to the door) "I GOT SHOTGUN!!"

Logan: "Nobody cares, you fucking fag."

Kalee: "He's such a shotgun fiend."
