Sporking/MSTing is the act of making fun of something, in this case, written work and other things.
If you see something of yours, a friend's, or something you're a major fan of, please . . . don't tell me 'cause I'm not going to care what you say, especially if it's negative, and that includes boo-hooing and throwing around threats in an attempt to intimidate me. I'm not going to take it down no matter what you say or do.
WARNING: I use extreme profantiy and I do spork badly written sex. You've been warned.
