What does the abbreviation SU stand for?
SU, or S/U, is a common internet slang that can stand for a variety of different things via text messaging or on social media sites like Snapchat and Instagram.
According to Urban Dictionary, SU can stand for “swipe up.” This is usually used in different frames of sponsored Snapchat or Instagram stories. Within these stories, the posters can advise their viewers to “swipe up” to view a link. This involves the user physically swiping up with their finger on the screen of the Instagram story. This will usually take the person to either a shop or website that the poster is sponsored by, or it will take them to the poster’s own website. People use these to either get more views, or to direct their audience to a brand that is sponsoring them.
Cyber Definitions states that S/U can also stand for “shut up.” This is a very blunt way for someone to tell another person to stop talking or to be quiet. While this may seem rude, it can also be used in a joking or teasing way between friends. For example, if one friend is teasing another about the person they have a crush on, the other one might reply “shut up!” This term can also be used as an exclamation or expression of bewilderment or disbelief, similar to OMG.
Finally, SU can also stand for “straight up.” While other people may be more common with the mixology meaning of straight up – without ice – when it comes to internet jargon, straight up means that one is telling the truth and being honest, per Urban Dictionary. If one questions someone’s honesty, they might respond with “straight up.”
According to Acronym Finder and The Free Dictionary, SU can also stand for a plethora of other meanings, however these are far less common. One should be very careful when using acronyms that have multiple meanings like S/U because if taken out of context, one may be confused as to what one means. Additionally, if they are only familiar with one specific meaning of SU, this could also cause confusion. Overall, one should ensure their context is clear when using acronyms like SU to avoid any confusion.
