When Justin Bieber returned to the stage at the 2015 Video Music Awards for an awesome medley of "Where Are U Now" and "What Do You Mean," we were super pumped. So were Beliebers everywhere. So was he.

On Tuesday, Biebs and photog pal Rory Kramer announced plans to keep the good-vibes train rollin' with a mini-Twitter experiment -- have fans record themselves lip-syncing and/or dancing to "What Do You Mean" and tag their vids with #whatdoyoumeanviral. This was all in hope of having the Belieber-created versions of the song blow the heck up on the web and, yep, go viral.

Fans wasted no time, recording their own takes on Justin's new song in their bedrooms, amid their Bieber shrines and even in places as far away as Madagascar.

Some opted for props to help get their clips a little more visual flair.

Of course, the dances were the most entertaining.

And not even a big-shot TV studio was immune to the phenomenon.

"What Do You Mean" truly is a family affair.

We imagine Justin's sitting in the "Tonight Show" dressing room right now, scrolling through his feed and swelling with pride for all his Beliebers across the world.
