Found yourself out and about in public or scrolling through social media and hearing the phrase '6-7' being thrown around.
Well, look no further, as we're here to give you a rundown on what this new piece of Gen Alpha lingo means.
Defined as children and teenagers born between 2010 and 2024, we have Gen Alpha and younger members of Gen Z to thank for the rise in 'brain rot' content taking over the internet.
Think 'Skibidi toilet' or 'fanum tax' and the general spectre of doomscrolling. The latest member of the nonsensical party is 6-7, also stylised as 67 or 6 7.
So what do these random numbers mean? Well, like a lot of Gen Alpha slang, absolutely everything and nothing.
6-7 makes no sense – and that's the point (Getty Stock Images) What are the origins of the '6-7 meme'?
A deep dive into internet history suggests that the 6-7 meme originates with US rapper Skrilla, who, in February this year, released a song by the name of 'Doot Doot (6 7)'.
You can listen to the track here if you wish, which includes the line '6-7, I just bipped right on the highway'.
The snippet was promptly used in TikTok sports edits, specifically ones featuring basketball player LaMelo Ball, who is 6ft 7.
So how did the phrase go viral?
The 6-7 meme came into its final form when content creator Cam Wilder posted a video showing his Amateur Athletic basketball team performing.
In the video, roughly around 13 minutes in, a kid can be heard shouting '6-7' over and over again while moving his hands up and down with the palms facing upwards.
He isn't the only face of the 6-7 meme either, with content creator and high school basketball player Taylen Kinney branding himself as 'Mr 67' after going viral for using the phrase while rating Starbucks drinks.
Kinney has even attempted to capitalise on the trend by launching his own drinks brand, 6 7 Water, which is marketed as 'your favourite hooper's water'.
As with any online meme, things have only snowballed from there, and 6-7 is now used by teenagers to mean pretty much anything they want it to be.
Kim's kids definitely taught her this one (NBC) 6-7 is now living out the traditional life cycle of a viral meme, with celebrities such as Kim Kardashian, singer Natasha Bedingfield and F1 racing driver Lando Norris even posting themselves saying 6-7 and doing the hand gesture.
Bedingfield even hosted a full circle moment for the meme, bringing Skrilla out to perform 'Doot Doot' on stage with her while she belted 6-7 into the microphone.
And now with the meme reaching peak popularity, we can only sit and watch as it dies an inevitable death.
