Save the flying unicorns!
One day I went to school and some people were protesting with signs that said "STFU." I asked them if they knew what it meant and they said it meant save the flying unicorns.

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?"
