A friend who only wants to hang out when he/she is in a good mood. They say that they'd rather not make their friends unhappy, and use this as an excuse to break off engagements on a moment's notice if his/her mood changes.
I was planning to hang out with Mike today, but he's such a fair weather friend that he called me five minutes before he was supposed to show up and canceled because he said he's feeling down.

A friend or acquaintance who flirts with others only when they do not have a more desirable romantic interest:
Sally and I have been hitting it off lately via text, even exchanging some salacious images. I thought for sure we were going down a path of romantic exploration, but now that her ex-boyfriend, Frank, is back in her life, she turned out to be a fair-weather flirt and won’t even reply to me.

A fair weather fisherman is an angler who only goes fishing when the weather is good or sunny. He never goes fishing when the conditions are uncomfortable. It is considered an insult.
