Get the Homer mug.
Being blindly devoted to your favorite sports team wether they are good or not.
Saying clearly untrue things about your favorite team (i.e. Jamarcus Russell was the best qb ever)
Should only be used in a derogatory way of describing an annoying fan (i.e. Lakers "fans")
person 1: I can't believe kobe didnt get that foul call, he got hammered there
Person 2: Dude, no one touched him, you can clearly see in the replay no one was within 3 feet of him
Person 1: Thats b.s. man its just the angle of the camera
Person 2: Classic case of homerism
