In sports, someone who shamelessly cheers for a particular team not because he likes them or follows them faithfully, but only because that particular team is the "popular" choice or has been or is the top team in their specific sport recently. When that team which bandwagoners follow falls from grace, they gleefully jump on the next teams bandwagon and cheer for that team.
All Lakers fans are bandwagoners, ALL OF THEM, except maybe Jack Nicholson.
Starting Power Forward for the Los Angeles Lakers. Known infamously for being a black redneck who enjoys such white trash things as 18wheelers & wrestling. Also known for being the dirtiest player in the NBA (use of the flying elbows to other people's head, his kickjumpers onto defender's nuts), he is the ultimate cheapshot artist and should die without an NBA championship. Since he could not lead his own team to the ring, he had to bandwagon onto the Lakers so that Shaq & Kobe carry his dirty ass to the title this year. A real grade A douchebag. Also picks on smaller guys & consistently fails in the clutch.
Oh my God, Karl Malone just elbowed some smaller guy in the throat!
