what does su mean

Short answer: SU (or S/U) is an informal shorthand that can mean different things depending on the platform and context. ([parade.com](https://parade.com/living/s-u-meaning?utm_source=openai)) 1) "Swipe up" / "Scroll up" — On story-based social apps (Snapchat, Instagram, TikTok) S/U most often tells viewers to swipe up or scroll up to see a link, extra content, or to open a page. This is common in influencer posts and promotional stories.

SU, no way!" 3) "See you" — Less commonly, SU can be a quick sign-off meaning “see you” (as in “see you later”). Context usually makes this clear.

If you’re unsure, ask the sender to clarify—it’s the fastest way to avoid misunderstanding.
