STFU

An acronym for Shut The Fuck Up. The illiterate mass that uses this seems to conveniently fail to realize that acronyms do not include a "T" for the article "the".

"If you ain't got nothing nice to say, then STFU."

"That's a double-negative."

"Huh, why do you speak in gibberish?"

STFU

The submission finishing move of John Cena. This hold is known in professional wrestling as the Stepover Toehold Sleeper (STS) and innovated by Masahiro Chono. The wrestler performs a stepover toehold and wraps his arm around the neck of the opponent as in a sleeper hold.

John Cena made Batista tap out when he applied the STFU.
