SU means “Swipe Up.” It’s a casual, social-media–friendly way of telling someone to open a link or view content by swiping up on a story or post.
What Does SU Mean in Text?
In texting and social media, SU usually stands for “Swipe Up.” People use it when sharing links, promotions, videos, or stories especially on platforms where swiping up opens content directly.

You’ll often see this abbreviation in Instagram Stories, Snapchat posts, and influencer content, where quick instructions are common.
In short: SU = Swipe Up = Open the link or story content.
