Mathew Morris is a 14-year-old kid from the US who is pretty famous in tween circles as MattyB. He's the star of the incredibly popular YouTube channel "MattyB Raps", which uploads videos featuring MattyB covering popular music.
In October last year, MattyB was famously "grounded from the internet" as part of a publicity stunt.
On the weekend, he took to Twitter to offer up some free advice to any of the couples out there: Matty was heading out for the day, and anyone who hoped to keep their girlfriend should think about trying to hide her.
Just to play it safe, Twitter user Jordy (@Zrowable) tweeted out a screenshot of his texts telling his girlfriend to hide. He couldn't tell her why, but dear god, he needed her to hide.
Jordy's tweet picked up more than 150,000 retweets and also spawned a bunch of other people tweeting their girlfriends, telling them to hide, lest they be drawn in by the allure of MattyB and his raps.
When the notorious tweet-stealing account Common White Girl had a crack, it only meant more people got involved.
And then even the words "hide your girlfriend... I'm heading out for the day" became a meme.
There's no word yet on whether any girlfriends were drawn into the irresistible pull of MattyB while he was out for the day – but time will surely tell. In the meantime, here's MattyB at church.
