Any guy seen on the Jumbotron at a sporting event, especially the dorky ones. Often seen sporting ridiculous headwear or a painted chest in his favorite team colors along with a line of other jumbodorks. Good for a laugh, jumbodorks only appear on the Jumbotron when a jumbobabe isn't available.
There is no way I'm painting my chest for the game; I don't want to make my Jumbotron debut looking like a jumbodork!
