What Does STFU Mean in Text?

STFU is an acronym that stands for “Shut The F* Up.”** Yep, it’s as direct as it sounds. People use it to tell someone to stop talking—or typing—usually in a joking, annoyed, or sarcastic way.

While its literal meaning might seem harsh, the tone really depends on the context. Among friends, it can be playful, like teasing someone for saying something silly. In a heated online debate, however, it’s considered rude and dismissive.

Sometimes, you might also see variations like:

• stfuu – an extended, dramatic version for emphasis
• stf – a softer, slightly less aggressive abbreviation
• STFU and… – used humorously to suggest someone stops talking before doing something else
