What Does MK, ICYMI, FYI & SCB Mean On Snapchat? Slangs Explained

Snapchat has almost 300 million daily users, reaching three out of four millennials and Gen Z youngsters in the United States.

Whether your teenager is texting on Snapchat or you’re a new Snapchat user yourself, you’ll likely come across various slang abbreviations, such as MK and SCB.

These slang abbreviations and acronyms are sometimes hard to figure out. There are so many possibilities as to what they stand for.

If you’ve ever felt confused by Snapchat slang, this article is for you. Today, I will be explaining lots of Snapchat slang meanings, and I’ll even give you resources to help you figure out the meaning of any slang acronym not on this list.

Let’s get into it.

In this section, I will be listing some of the most common Snapchat slang terms and explaining what they mean. Bookmark this article and use it as your personal “Snapchat slang dictionary.”

What Does MK Mean on Snapchat?

On Snapchat, MK is usually an abbreviation of “Mmmm, OK!”

There’s a crucial difference between MK and OK. A regular OK just means “okay” – nothing more, nothing less.

However, MK means you are adding the “mmm” before the “okay,” which gives it a whole new meaning. Someone might text “MK” when they don’t really believe what the other person is telling them – something like, “Okay, if you say so!”

They might also use MK to express disinterest – like, “Okay, whatever!”

Among Spanish speakers in the United States, MK can also stand for “Marica,” which is a slang word that people use to address their close friends in some Spanish dialects. It can be offensive in other dialects or when talking to someone who is not your close friend.

Among gamers in the US, MK can also stand for Mortal Kombat.

For the most part, however, you can assume that MK means “Mmm, okay,” unless the context indicates otherwise. MK as a standalone text almost always means “Mmmm, okay.”

What Does ICYMI Mean on Snapchat?

ICYMI stands for I See You Missed It. In this case, each of the letters represents the first letter of different words, except for the letter C, which is a way to express the word “see” in text messages.

You can use ICYMI in various situations. Typically, you would use it to tell a friend that they missed your snap – on Snapchat, you can see if someone opened the snap you sent them or not.

After writing ICYMI, you can then explain exactly what your friend missed.

If someone texts you “ICYMI,” they might be trying to tell you that you haven’t opened one of the snaps they sent you.

People might also use ICYMI to tell you that you missed anything, such as an event, news update, class, or test.

ICYMI has another possible meaning: In Case You Missed It. Someone might be informing you of something, like a school update, that you might have missed.

What Does FYI Mean on Snapchat?

FYI means For Your Information. People use FYI at the beginning of a Snapchat message to say something like, “Well, just in case you didn’t know, you should know about this-and-this.”

FYI can sometimes be passive-aggressive. People often use it to express surprise and incredulity that the other person doesn’t know a basic fact.

People also use it in arguments when trying to prove a point.

However, FYI doesn’t necessarily carry any negative connotations. It all depends on the context – people can use it when expressing incredulity at something someone has done, for example.

FYI is not an abbreviation that is exclusive to Snapchat, by the way. It is used on WhatsApp, in SMS messages, and on many types of chatting apps.

Interestingly enough, the origins of FYI go way back to the first half of the 20th century, when people were still sending telegrams.

FYI still meant For Your Information, but its intentions were slightly different – it was used to indicate that the contents of the telegram were for the recipient only and not to be read by others.

What Does SCB Mean on Snapchat?

SCB stands for Snapchat Back and is an abbreviation that is unique to Snapchat. Typically, if someone writes SCB to you, it means they want you to “snap” them back and reply to their message.

SCB can signify urgency or simply that the person wants to maintain a streak on Snapchat with you. Sometimes, people will text SCB when they’re simply in the mood for chatting – it doesn’t always indicate urgency.

Other Slang Abbreviations

ESB stands for Everyone Snap Back and is another abbreviation unique to Snapchat. People will use ESB in their Snapchat stories.

Snapchat pioneered stories back in 2013. Stories are posts that are visible to all of a Snapchat user’s friends – but they only stay up for 24 hours.

Facebook and Instagram now allow you to post pictures or video stories too.

When someone writes ESB in their story, it means they want everyone who sees their story to reply. They are probably bored and want to chat with as many friends as possible, or they might simply be looking for everyone’s opinions on the post they just shared.

What Does NRS Mean on Snapchat?

NRS stands for No Replies, and it has the opposite meaning of ESB.

If someone writes ESB in their Snapchat story, it means they want everyone to reply. However, when someone writes NRS in a Snapchat story, it means they don’t want anyone to reply.

Why not? There could be many reasons – perhaps they are busy, perhaps they are not in the mood to argue about what they posted, or perhaps they are going offline or have limited data and won’t be able to respond.

What Does AMOS Mean on Snapchat?

What Does BRB Mean on Snapchat?

What Do GMS and GNS Mean on Snapchat?

GMS stands for Good Morning Streaks, while GNS stands for Good Night Streaks.

Snapchat streaks are a feature that motivates users to continue using the app. A streak is when you and your friend have been sending each other snaps at least once a day for consecutive days.

So, if you have been snapping each other every day for seven days, you have a seven-day streak.

You don’t win anything of substance from maintaining streaks. However, you do get a special emoji that appears next to your and your friend’s names in each of your phones.

Many teenagers love maintaining streaks. It’s fun and mostly harmless – although it can be addictive and time-wasting when you’re trying to maintain streaks with many people at the same time.

You and your friend only need to snap each other once a day to keep the streak going. The problem is that missing even just one day can ruin your streak, forcing you to start your streak all over again.

To avoid that, many users send each other snaps once a day, either in the morning and at night, to ensure they maintain their streaks. They might snap multiple people at the same time, depending on how many people they are “streaking” with.

You can send a snap of anything – the sky, a building, or even the floor. The point is simply to maintain the streak.

People will often include the message GMS or GNS in their daily snaps, depending on the time of the day they send it.

Those acronyms inform the other user what the purpose of the snap is so they don’t think the other person is trying to annoy them with pointless snaps. It also reminds you to snap them back so you don’t lose the streak.
