Sandy Turd Flex (STF)

When you're taking a dump and your butt flexes forcing the poop to retract into your butthole causing the sensation of sandpaper going up your butt.

"Man I hate it when I have a sandy turd flex (STF) in the bathroom"

STFUAR

Shut The Fuck Up And Ride

Cyclists on the Internet are prone to getting into tedious arguments about the most ridiculous things. STFUAR refocuses them on what is important.

Person 1: That route we took was terrible! Who is leading this trash, and were you dropped on your head as a child?

Person 2: STFUAR
