Multimedia instant messaging platform Snapchat contains certain SU terms which some users have been left confused about.
Snapchat has been a popular way for people to communicate for a number of years now and different acronyms and slang terms are widely used as form of effective communication.
For those out of the loop SU means 'Swipe Up' and this feature gives one an option to send a private message to the original poster of the story.
It can also be used as a source of invitation for people to send that person a message. Alternatively users may embed links to the stories and Swiping Up will allow you to access it.
Across other platforms including Snapchat, SU can also mean Shut Up, a major slang commonly used.
