Nope, never heard of it.
Well, a YouTuber by the name of Sam Pepper uploaded a video called "Fake Hand Ass Pinch Prank" in which he wore a hoodie which looked lik his hands are inside, but his hand is sticking out from the bottom and he pinches a number of girls' butts as a "prank". And many people are getting on him because it's just plain sexual harrassment. It got to the point that YouTube took down the video after many people reported it.
You'd think he'd learn, right? WRONG! He uploaded a second part in which one of his female friends does the same trick to guys. That video had to be reported and taken down as well. And then he uploaded a third part saying that it was all "staged" and that he wanted to show that it's not just women that gets abused like this and that he's trying to raise awareness on abuse on both genders. You know what I think? I call "bullshit". It looks like a sloppy way to cover up what he did. The fact of the matter is is that had he left it at just that video, he's telling people "It's okay to sexually harrass people as long as it's a prank". Also, considering that people have said that he's very arrogant and a fame whore and the fact that he's done bad stuff in the past (lassoing girls who are not acquainted with him and then kissing them), I'm not buying it one bit.
