A fan of a sports team who only shows support when the team is doing well. During hard times they usually bandwagon other teams. They basically have no real loyalty to the team, but still manage to get better seats than you at the game. Strangely they mysteriously vanish at the first sign of trouble.
Fair weather fan: "OMG what a comeback! That was amazing!"

Regular fan: "How would you know? You left right when Favre threw the pick six in the 2nd and if I recall you didn't even start rooting for Green Bay until 2 weeks ago."

Fair weather fan: "... GO PACK!"

(After the playoff game the fair weather fan immediately became a Pats fan and stowed all Packer memorabilia away.)

Fair Weather Fan's creed:
Last to join, first to leave.

Certain people who only watch a sports team when said sports team is having a winning season.
unfortunately for me; Miami Heat, Florida Marlins, and Miami Dolphins fans are fair weather fans.

New Dats. A sickening majority of 2009-2010 Saints Fans who couldn't stand the saints or the NFL for most of the season. The last 8 weeks this fan has bought 10 shirts, a jersey and hotel room in the quarter to proclaim how much they love the saints and leech off the joy felt by the who dats. In other words they are about as cool as a fanny pack.
New Dat: Stand up and get what
Who Dat: it is Stand up and get Crunk
Who Dat 2: who in the fuck is that?
Who Dat: Another fucking New Dat
Who Dat2: Where were all of them 8 weeks ago?
Who Dat: Leaching of the corndogs at LSU. Don't worry they won't be here long.
Who Dat 2: Good I hate the fair weather fans, they are fucking useless and they are raising the ticket prices.

A rubbish follower of a team that won’t ever bet his friends when it comes to his or her team.
Rick won’t bet anything on his Seminoles because he fears his team sucks and can’t win. He is now a fair weather fan because he stopped believing in his team.

1. A fan who only likes a team when it is winning
John used to like the Mariners but now that they have been losing a lot he now likes the Dodgers. He is such a fair weathered fan

A self-proclaimed fan whose loyalty and dedication is easily swayed
Drew claims to be a diehard Red Sox fan, but the fact that he chose to watch an episode of Game of Thrones over a Red Sox - Yankees game proves that he's just a fair weather fan.

People who only support sports teams when they are doing well ie when the "weather is fair." If their team is losing, they don't claim to be a fan, but when their team is winning, they are obnoxious to the highest degree.
"Florida (Gators) are such fair weather fans, you don't hear shit from them unless they're winning."

"Georgia (Bulldogs) are the opposite of fair weather fans, they are DAWGS to the core, win or lose."
