World Cup Fag
A person that only watches soccer during the World Cup because it's en vogue, and is "sociably cool". World Cup fags never watch regular season games, never know anything about the teams prior to watching the World Cup, but always act like they've been following the sport for their entire life.
"Look at those fags outside playing soccer. They were just playing basketball the week before the World Cup."
"Yeah, that's because they're World Cup fags!"

"Look at those douches with three flags on their cars. They don't even play or watch soccer. Fucking World Cup fags."
