Most are know criminals (felons) and/or clinically diagnosed mentally ill (retards) that live outside the L.A. or Dallas areas and are misguided hangers-on to past decades when those teams may have had a modicum of talent and/or luck. Their illogical & persistent affiliation with the team is most directly attributed a missing chromosome that also appears to result in excessive body tattooing, domestic violence, binge drinking, bed-wetting, drooling and an unexplained need to wear over-sized and excessively dark sunglasses (maybe out of embarrassment).
Both groups are made up of delinquents, reprobates, malcontents, and blow-hards that are the scourge of all true sports fans. Extreme cases are evidenced by a trip to their "mecca" (stadium) to demonstrate their loyalty & obtain a pathetic photo of them wearing a blue team jersey while holding up one finger that they can later post as a testament to their senseless dedication.
Father: There are lots of them honey, but the one that best describes would be the felons and retards in blue or bluetards.
Daughter: Do you mean the Dodger fans or the Cowboy fans?
