MST

Mystery Science Theater. When people sit in front of the screen to any movie, the cheesier and more B-grade the better, and make snarky comments.

This can also be done with fanfic by inserting text every so often to point out gross errors in characterization or whatever.

Beavis and Butthead MSTed lots of music videos from their couch.

The Protectors of the Plot Continum MSTed several fics where bad authors had wreaked havoc on canon.

MSTS

Mississippi State Titty Shake. This is the dance done when MSU beats UF. It involves jumping up and down while chanting "Mississippi State....Mississippi State."

Hey Clunt, did you just see your cousin doing the MSTS?

MST

To parody a la Mystery Science Theater 3000

Honestly, I'd rather sit through a John Agar film festival than another Gonterman story.
