On Snapchat, SB means “Snap Back,” a request to reply to a Snap—often to keep a Snap Streak active.
It’s a commonly used abbreviation that asks someone to reply to a Snap—usually to continue a conversation or keep a Snap Streak alive.
Snapchat users rely heavily on short abbreviations to communicate quickly, and SB has become one of the most frequently used reminders in daily Snap exchanges.
What Is “Snap Back” on Snapchat?
“Snap Back” simply means reply to a Snap with another Snap.
Snapchat tracks how many consecutive days two users exchange Snaps through its Snap Streak feature. If either person fails to send a Snap within 24 hours, the streak ends. Sending “SB” is a casual nudge to prevent that from happening.
In simple terms:
- SB = “Reply to my Snap”
- Often used when:
- A reply is delayed
- A Snap Streak is about to break
- Someone wants to keep the interaction going
Why Do People Use SB on Snapchat?
People use “SB” mainly for three reasons:
To Maintain a Snap Streak
Snap Streaks are important to many Snapchat users. SB helps remind the other person to respond before the streak expires.
To Prompt a Response
If someone hasn’t replied for a while, SB acts as a polite follow-up instead of sending a long message.
To Keep Conversations Active
SB keeps chats from going cold and signals continued interest in interacting.
Examples of SB Used on Snapchat
Here’s how SB typically appears in real conversations:
- “SB?” – Asking someone to reply
- “SB pls” – Friendly reminder
- “Don’t forget SB” – Streak reminder

Best practice:
Use SB only with friends who understand Snapchat slang. Overusing it can feel pushy.

Responding with a Snap—not text—is the best way to keep the streak active.
