A guy who plays Madden all the time and talks of nothing else. He has probably never seen a real football in his life, or doesn't have enough friends to play even a casual game outside. He will run out to buy the new Madden games the minute they release, and will always proclaim this year's game is totally better than last year's.
"Dude, Joe is such a Madden Fag. I don't think he's ever picked up another game in his life."
