A couple who you usually see at the State Fair where the dude is really crappy and is wearing a beater, while the chick is gorgeous and is out of the guy's league
Tony: Damn, that chick is fiiiine, too bad she's with that douche bag
Brandon: I know, that's so State Fair Syndrome
or
Britney Spears and K-Fed

"What the fuck! You fucked my girlfriend, killed my dog, stole my life's savings and burned down my house! I thought you were my friend!"
"Hey, life ain't fair, man."

A friend who only associates with you when they have nothing better to do. Someone who may only stick around in exciting situations but when times are somewhat boring, leave your side.
A fair weather friend would act like they want to hang out but never invite you to do anything and if you invite them to do something they will only do it if they cant find something better.

Someone who you thought was a good friend but they only show up when the circumstances are in their favor.
At first I thought Matt was a good friend because he would always hang out. Turns out he was just a fair weather-friend. Boy it is mighty cloudy today.

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.

A friend who is only a friend when circumstances are pleasant or profitable. At the first sign of trouble, these capricious, disloyal friends will drop their relationship with you.
I had thought Ted would stand by me when I was accused of theft, but it turned out he was only a fair-weather friend.

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.
