Also known as "Fair-weather fan".

People who only support sports teams that recently win championships and then claim they liked that team all along. These people can be highly annoying, approaching them may result in increased levels of stress and aggression. Frontrunners may claim they have a relative or were born in the state where the winning team is from. Do not trust them at any cost.

Get the frontrunner mug.
1. someone who gives up when the going gets tough
2. When a team is facing an early deficit, for example a 28-7 deficit in the first quarter, a front runner will throw in the towel and tell his wife to not show up to the game
Steven might be a frontrunner because when his team gets down early he often believes his team won't come back and we should just give up

Bandwagon sports fans that will only root for a team, based on their success.

Patriots, Warriors, Yankees, Cowboys,and Lakers fans.
"All Patriots fans will claim they've been diehard fans since Drew Bledsoe but the rest of the country knows they're a bunch of frontrunners, that only started liking them once they started winning in 2001."
