Screwed In Fantasy. The act of being screwed in a fantasy sport by a fantasy sports player. Then, going to screwedinfantasy.com and posting to make sure that all of your friends and foes read about it.

How you can get screwed: Your fantasy catcher gets benched on Sunday and you lose by one hit, giving your nemesis the week's victory. Your top notch wide receiver doesn't grab a catch on Sunday, costing you a valuable 10-15 fantasy points. Your favorite basketball player steps on someone's foot and is out for 4-6 weeks. Your fantasy hockey player misses the game winning shot, and your chance at a fantasy championship.

The list goes on and on.
I took Joe Nathan in the 10th round of the draft after two other closers went, knowing Nathan was a guaranteed 40+ saves a year. One week later he goes under Tommy John surgery and I'm out of a player and a solid draft pick. You really S.I.F.'ed me on this one Nathan.
