Spanish percussionist, Jorge Pérez, became both popular and unpopular last year, after a music video of him slapping bottoms went viral on YouTube.
We have two issues with this new 'genre'.
First of all, it looks painful.
Secondly, it's extremely sexist. Why does he only slap women's bottoms? And not just any old women's bottoms - really attractive, slim, toned women's bottoms?
He claims that all of the bottom's he slaps belong to his friends, but it's still really creepy.
What do you think of the instruments?
