Fairweather Fan 

A sports fan that never sticks with one team. His/her loyalty is always in question because he/she only pulls for the hot teams at that time.

Dylan was a Stanford fan last week but because they lost, he now pulls for Oklahoma State which makes him a Fairweather Fan.

His favorite team didn't Slang That Eppley so he is pulling for someone new today.
