Someone, usually a jumbodork, who monopolizes or steals Jumbotron time (jumbotime) from an intended jumbotarget (jumbobabe, jumbodork) who is oblivious of their sudden jumbofame at a sporting event.
Look at that jumbobabe! She has absolutely no awareness of the crazy jumbohog/jumbothief behind her! How blonde can you get?
