The most common meaning of FS is “for sure” on Snapchat.

It usually means “for sure” over text, on Instagram, and on TikTok as well. In this context, FS is used to agree with someone, confirm information, or emphasize something. As a note, “FS,” “Fs,” and “fs” all typically mean the same thing. You might say:

  • “Are you FS going to call me tonight?”
  • “I don’t know FS, but I think unit 2 is definitely on the test.”
  • You: “You’re looking to buy a PS5, right?” Them: “FS.”

It could mean “f*cks sake” on Snapchat depending on how it’s used.

FS is also commonly used this way on Instagram, TikTok, and over text. If someone seems unhappy or annoyed, they’re probably using FS to mean “f*cks sake.” This expletive phrase sort of means “oh golly!” or “you’re kidding me?!” Someone might say:

  • “FS, I heard Jenny was talking trash.”
  • “For FS, why wouldn’t you tell me you’re going to the Drake concert?”
  • You: “Just FYI, I was wrong. We totally had homework.” Them: “FS, Andy…”
  • You may see “fFS” occasionally. This is shorthand for “for f*cks sake.”

What does FS mean on Facebook Marketplace?

On Facebook Marketplace, FS means “for sale.”

You may see this usage of FS on Craigslist or other sites where people sell things. You’ll likely see “FS” or “FS” at the beginning of a list or short sentence about what the person is trying to sell (as a note, “obo” after a price means “or best offer”). You might see someone write:

  • “FS: used gaming PC with keyboard and mouse. $600 obo.”
  • “Does anyone have a bar cart FS?”
  • “FS—Nike Air 11s.”

How to Use FS (“for sure”)

Respond to questions with FS to answer in the affirmative.

If someone asks you a question and there’s an implied answer built into the way they phrased it, you can answer with FS to confirm their question. You can also use FS just to generally respond with a “yes” if you’d like. For example:

  • Them: “You have an extra calculator I can use tomorrow, right?” You: “FS. I got you.”
  • Them: “Are you going to prom?” You: “Oh, FS.”

Use FS to emphasize the way you feel about something.

This way of using FS is similar to the way you’d use “definitely” or “totally.” This is a casual way to put a little bit of weight on whatever point you’re making. You might say:

  • “I rock with The Weeknd’s new record FS.”
  • Them: “You like Wendy’s, right?” You: “FS. Absolutely the best fast food out there.”

Try using FS to agree with someone’s perspective.

You can also use FS to imply that you’re on the same page as someone. If you’re chatting with a friend and they throw out an opinion you like, you can use “FS” the same way you might say, “I agree.” For example:

  • Them: “I can’t stand Mr. Harrison. His lectures are so boring.” You: “FS. I feel like I fall asleep halfway through every class.”
  • Them: “I really like hanging out with Melissa. She’s such a fun time.” You: “Yeah, FS. I like her, too.”

How to Use FS (“f*cks sake”)

Add an FS to your response to indicate annoyance.

If someone says something that bothers or frustrates you, a simple FS will communicate the way you feel. You can even use FS on its own as way of going “I’m p*ssed!” or “God d*mn!” You might say:

  • Them: “Hey, uhhh…I need you to come pick me up.” You: “FS…I’m busy rn. Can’t you ask someone else?”
  • Them: “I forgot to bring my lunch money. Can you cover me today?” You: “FS, Alex. I barely have enough for me…”
