You’ve probably been scrolling through Snapchat or reading someone’s story when suddenly you spot a message that says “s/u for details” or “new update—s/u!” And if you’re seeing it for the first time, your brain does a little pause like… “Wait—what? Is this a typo? A hidden code? Did I miss something?”
Don’t worry — everyone has that moment. Slang moves fast, especially on Snapchat, and s/u is one of those short forms that’s super common but not immediately obvious.
Quick Answer: S/U means “Swipe Up.”
It’s a casual and social-media–friendly way of telling someone to swipe up on a story to open a link, view more content, or respond.
🧠 What Does S/U Mean in Text?
S/U stands for “Swipe Up.”
It’s used mostly on Snapchat and Instagram Stories where creators, friends, or brands tell viewers to swipe up to see more—like a link, a form, a message, or extra information.
Example:
“New vlog is out! S/U to watch 👇”
It’s basically a quick call-to-action that encourages you to interact with the story.
In short: S/U = Swipe Up = a quick way to say “swipe for more info.”
📱 Where Is S/U Commonly Used?
S/U is mainly seen on platforms that support the “swipe up” feature—usually tied to stories or short content.
Here’s where it’s most popular:
- 📸 Snapchat Stories – The #1 place you’ll see it
- 📱 Instagram Stories (older version; now replaced with link stickers)
- 🎥 TikTok (sometimes in captions meaning “swipe up for part 2”)
- 💬 Text Messages (rare—but some people still use it casually)
- 🛍️ Brand Stories/Ads (to open links, shop items, or sign up)
Tone:
S/U is always casual and used only in social-media contexts.
It’s not formal and not used in professional chatting.
