Have you ever seen someone text or snap you with “SU” and wondered what it means? 🤔 You’re not alone!
In today’s fast-moving online conversations, abbreviations like SU pop up everywhere — from Snapchat stories to DMs and group chats.
Let’s break down exactly what SU means in text, how it’s used, and when you should use it too.
🔍 What Does SU Mean in Text?
The abbreviation SU most commonly stands for “Swipe Up” 🚀. It’s a call to action used on platforms like Snapchat, Instagram, and TikTok to tell viewers to swipe up on the screen to access a link, post, or more content.
💬 Example: “New video is live! SU to watch 🎥👇”
However, in texting (outside of Snapchat), SU can also mean “Shut Up” — but not always in a rude way. It depends heavily on the context and relationship between the people chatting.
💬 Example: A: “Guess what? I just won $500!” B: “SU! No way 😂”
So, the meaning of SU changes depending on the situation — it can be friendly, playful, or promotional.
📱 SU Meaning on Snapchat

Creators, influencers, and businesses frequently use “SU” to drive clicks and engagement. It’s short, eye-catching, and works perfectly with social media language.
