Actually, “STFU” is an Initialism, Not an Acronym.
Remember that an acronym is pronounced as a single word, whereas an initialism is pronounced as a series of letters. So when you say “I’ve got an acronym for you, buddy: STFU!”—well, you’re actually working to erode that distinction. It’s not as if one can pronounce the word “stuh-foo” or something. That would sound quite ignorant.
What’s that? You say you want me to “literally” shut my fucking face?
McSweeney’s is just fantastic.
