STFU Meaning

What Does STFU Mean?

“STFU” means “shut the fu** up.”

This phrase is definitely one that can cause a lot of drama in communication. Due to the profanity contained within this phrase, it should not be used in professional communication.

Other similar slang terms

Although “STFU” is by far the most commonly used type of acronym for telling others to “shut up” or not to bother someone, there are a few other variations.

First, we have “STHU” which means “shut the hell up.” This one, even though it’s still considered rude, may be safer for work because “hell” is often viewed as not being as forceful as “fu**.”

Next is “STSU.” This version means “shut the sh** up.” Again, this version is a little weaker than “STFU” but it still should not be used in professional settings because it contains profanity.

It is commonly used in social media, texting, messaging, forums, and online gaming. It is used to tell someone to stop talking and is generally taken as a sign that someone doesn’t want to interact with another user anymore because they have become upset or no longer wish to engage with the other party.

Conversation Examples

Here are some examples:

Example 1:

  • Gamer 1: Good game, you really suck tho bro. Go practice some more and next time maybe you’ll have a chance.
  • Gamer 2: Man, STFU, your team carried you.

Our first example of this texting abbreviation shows two gamers talking after a match. The first gamer states that Gamer 2’s skills are lacking and that he needs more practice. Gamer 2 tells Gamer 1 to “STFU” as a sign of displeasure with his assessment.

Example 2:

  • Texter 1: Hey, what’s with all the noise? Can you STFU? My kid is trying to sleep over here.
  • Texter 2: That’s not me. I think it’s Barry, he has been having a lot of friends over lately. Want me to get him to STFU?

This second example shows this internet slang term being used in texting but concerning a problem that is off-line. Texter 1 is being bothered by loud noises. This situation most likely comes about in apartment buildings. She sends a text to her neighbor. By asking the neighbor to “STFU” in this context, she is asking for him to “keep the noise down.” The neighbor states that it wasn’t him making the noise and gives information about who it may be. By offering to get Barry to “STFU,” Texter 2 is offering to get Barry to make less noise.
