A ridiculous sports fan combining front running for both the raiders and Brett Favre. A grant walker usually tends to not believe they should be classified as such because "they didn't know what frontrunning was when they were 5".
These fans are made even more despicable by their tendency to banter inappropriately with good decent fans of local teams.
Look at that guy at the bar in the raiders hat and Favre jersey. He's such a grant walker
