Snapchat Slang Decoded: GMS, WTM, ESB, FS & More (2026)

Open any Snapchat group chat and you'll hit a wall of letters — GMS, WTM, ESB, FS — fired off like everyone already agreed on the dictionary. They didn't; you just pick it up. If you've ever nodded along to an abbreviation you didn't actually know, here's the plain-English version of the Snapchat slang you'll run into most in 2026.

The big ones you'll see daily

• GMS — Good Morning Snap (or "good morning, streaks"). The morning Snap people fire off to keep streaks and conversations alive.
• GNS — Good Night Snap. The evening bookend to GMS.
• WTM — What's the move? As in: what are we doing tonight, what's the plan.
• SFS — Shoutout for shoutout. You post their username, they post yours. Full breakdown in What is SFS on Snapchat.
• S4S — Streak for streak. Same energy as SFS, but you're swapping daily streaks instead of a one-off shoutout. See Streak for Streak explained.
• FS — For sure. Plain agreement.
• ESB — Everyone snap back. A nudge to a group to actually reply.

The "send it back" family

A lot of Snapchat slang exists for one reason: getting people to reply so streaks and stories stay alive.

• NRS — No replay snap. Reply, but don't screenshot or replay it.
• SB — Snap back. Send one in return.
• HMU — Hit me up. Slide into the chat.
• STREAKS — used as a verb: "wanna streaks?" means "want to start a Snapstreak?"

Status and friendship slang

• BFF / #1 BF — your best friend on Snapchat, the person you Snap most. The app tracks this with the 💛 yellow heart — see Snapchat emoji meanings.
• Streak — the 🔥 fire next to a name, counting consecutive days you've both Snapped.
• Half-swipe — peeking at a message without "opening" it. Whether it notifies them is its own rabbit hole: does half-swipe notify them?
• Planets — the Snapchat+ Friend Solar System that ranks your closest friends. Order and meaning in Snapchat Planets explained.

A quick word on the cringe-but-real ones

Some abbreviations are just shorthand, but a few are used to pressure people — "send X back or the streak dies." You never owe anyone a Snap, a screenshot, or anything else. If a chat feels like an obligation instead of a connection, mute it. Real friendships don't run on threats over a fire emoji.

Slang changes every few months. The throughline never does: people use it to stay connected. Learn the words, but chase the actual conversations.
