Fantasy Whore
Any player in the NFL that contributes nothing towards his team's win but puts up a great amount of fantasy points from scalping touchdowns at the goalline or running up the score when you're already up 50. Anyone in the top 10 fantasy points for running backs without 1000 rushing yards is a fantasy whore.
Tom Brady, Lendale White, Matt Forte and Marshawn Lynch; all can be defined as a fantasy whore.
Fantasy Whore
A girl you want to fuck but will never get. She lives in your fantasies and you fuck her every day until the frustration of never having her takes over your head and you start thinking of a new fantasy whore. Fantasy whore you try to forget can come back in while jacking off at any given time.
"What took you so long in the bathroom?"
"Jacking off to the fantasy whore."
"Jacking off to the fantasy whore."
