If you’re a Snapchat user, chances are you’ve come across some Snapchat slang. But as it evolves, it can be hard to keep track of it all. Here’s everything you need to know about the new Snapchat lingo.

Multimedia instant messaging platform Snapchat was initially released in 2011, and since then, it has gone on to become one of the top social media apps used by millions across the world.

On the app, you can send videos, pictures, and direct messages to your friends, as well as post stories, which automatically disappear after 24 hours.

Like any other social media apps, there are several different slang terms that are used on the app, some of which are unique to Snapchat and others that were originally popularized elsewhere.

If you’re confused about some of the words you’re seeing on Snapchat, here’s what you need to know about some of the app’s most popular terms.

What does SU mean on Snapchat?

On Snapchat, SU usually means ‘Swipe Up.’ When you swipe up on a story on the app, you can easily send a direct message to someone, so if someone uses this term, they may be encouraging you to message them.

Alternatively, people can put links in their stories, and if they write SU, they may be encouraging you to access the link. SU is also often written as S/U.

What does TTM mean on Snapchat?

TTM is an acronym that often stands for ‘Talk To Me.’ If someone sends you this term on Snapchat, they may be encouraging you to start or continue a conversation with them. You will most likely see this term used in direct messages, but it can also be used in public stories.

This term is used, not just on Snapchat, but on other platforms like WhatsApp, Instagram, Facebook, and more too.

What does LMR mean on Snapchat?

LMR is a term that means ‘Like My Recent.’ A ‘recent’ refers to the latest post you have uploaded to a social media platform, usually Instagram or TikTok.

On Snapchat, people may upload a story including a screenshot of their recent, along with the term LMR, to encourage their friends to go and engage with their latest social media post.

What does streak mean on Snapchat?

A Snapchat ‘streak’ refers to how many consecutive days you have exchanged snaps with another user on the app. You will see a number next to their name indicating how long your streak is.

Some users send images just containing the words ‘streaks’ to maintain their streaks with users for as long as possible.

What does ESB mean on Snapchat?

What does NRS mean on Snapchat?

NRS usually stands for ‘No Replies’ on Snapchat. This is often used as a way to let people know that you won’t be responding to Snaps for a period of time, whether that’s because you have no internet, or because you just don’t want to. This abbreviation can also take the form of NR.

What does SR mean on Snapchat?

SR usually stands for ‘Slow Replies,’ and is used as a way to let your contacts know that you won’t be replying as quickly as you usually do for whatever reason. It is used in a similar way to NRS, which means ‘No Replies.’

The term is also used outside of the instant messaging app to mean ‘Shoutout For Shoutout,’ and can also stand for ‘Spam for Spam.’

What does MB mean on Snapchat?

On Snapchat, MB usually stands for ‘My Bad.’ This expression is used to either apologize to someone or to simply admit that you have made a mistake. It’s often used to make things a bit lighter.

You will see this term both in direct messages and in public posts such as stories on Snapchat and Instagram, or the case of video platforms like TikTok, in video captions.

What does OTP mean on Snapchat?

OTP has multiple different meanings across the internet, but on Snapchat, it is commonly used to mean ‘On The Phone.’

You are most likely to see it used this way in a private message. For example, if you want to talk to someone but they are too busy, and they want to let you know that they are on the phone. It could also be used when someone is asking to talk to you on the phone.

However, across TikTok and many other social media platforms, OTP is also commonly understood to mean ‘One True Pairing.’ A term fans use to talk about their favorite TV, film, and book couples and pairings.
