I still remember the first time someone sent me “FS” in a chat. We were having a normal conversation, everything was going smoothly, and suddenly they replied, “Yeah, FS.”
I just stared at my phone thinking, “FS? Phir yeh konsi new cheez hai?” 😅
For a moment, I felt completely lost. I didn’t want to look silly by asking what it meant, so I did what we all secretly do—I tried to guess. First I thought it meant “For Sale,” then maybe “For Sure,” and then I wondered if it was some inside joke I completely missed.
Eventually, I asked a friend, and that one small moment saved me from a lot of confusion later.
Turns out, FS is most commonly used to mean “For Sure.”
Simple. Casual. Friendly. And honestly, once I learned it, I started seeing it everywhere.
So if you’re confused right now, don’t worry — I’ve been exactly where you are, and I’ll help you understand it the way I figured it out myself.
