Introduction
Ever scrolled through Snapchat or Instagram and spotted someone post “S/U 👀” — and had no idea what it meant? You’re not alone! The first time I saw a story captioned “New vlog! S/U 🔥”, I thought it was a new emoji trend. Turns out, it’s one of the most common social-media abbreviations used to drive clicks and engagement.
Quick Answer: “S/U” stands for “Swipe Up.” It’s a friendly and casual call-to-action slang mostly used on Snapchat and Instagram stories to tell viewers to swipe up to view a link, video, or product.
🧠 What Does S/U Mean in Text?
“S/U” means “Swipe Up,” a phrase that became popular on Snapchat when users could attach links to their stories. Viewers would literally swipe up on the screen to open that link — hence the abbreviation.
It’s often used in influencer captions or casual posts, like:
“New blog out now ✍️ S/U to read!”
Over time, “S/U” also made its way into DMs and group chats to hint at “check this out.”
In short:
👉 S/U = Swipe Up = View or open a linked post.
Origin Insight:
