This video clip of a performance by an up-and-coming UK rapper called Devz has become a huge meme since it was uploaded last month.
It's the "who what where" part that has people hooked.
It's the perfect response for all those time you are left kinda speechless.
Or the times you get asked loads of questions.
Lotes, the 28-year-old founder of YouTube channel Bl@ckbox where the video was uploaded, said the song had been recorded six to eight months ago and he had known immediately how catchy it would be.
Lotes said he wasn't worried that the song has become a giant meme.
And people who love the meme are actually starting to love the song.
The video has gone from having 2,500 views on Friday to more than 60,000 at the time of publication.
Lotes said that after seeing someone calling for the song to become Christmas No.1 they are now campaigning to make it a reality.
Who knows? In 2016 anything can happen.
