You’re scrolling through Snapchat or Instagram and suddenly someone posts:
“S/U for a shoutout!”
Or a friend messages:
“S/U if you wanna know 👀”
And you pause for a second thinking… What does S/U even stand for? Is it a question? A command? A sign-up sheet?
Don’t worry — it’s one of the most common short forms used on Snapchat and social media.
Quick Answer:
S/U means “Swipe Up.”
It’s a simple way of telling someone to swipe up on a Story or message to see more, reply, or access a link.
Let’s break down exactly how it works, where it’s used, and what it means in different contexts.
🧠 What Does S/U Mean in Text?
S/U = Swipe Up
It’s used mostly on Instagram Stories, Snapchat Stories, Facebook, and TikTok to tell viewers to swipe upward to open a link, send a message, answer a question, or view more details.
Example:
A: just posted my new vlog
B: oh bet, s/u link?
A: yup check my story!
Sometimes creators also write:
- “s/u for shoutout”
- “s/u to ask”
- “s/u for details”
In short:
👉 S/U = Swipe Up = access more info or respond by swiping.
🗓️ Origin & Evolution of “Swipe Up”
“Swipe Up” started as a gesture command on early mobile apps, but it became huge when:
- Snapchat introduced Swipe Up for messages & replies
- Instagram launched Swipe Up links for creators and brands
- Influencers used it to promote products, videos, giveaways, etc.
By the late 2010s, S/U became a common abbreviation because writing “swipe up” in every story took too much space.
Even now — even though Instagram moved mostly to link stickers — people still use S/U as slang for “reply,” “interact,” or “open.
