I've seen a couple of Power Slap videos that were fed to me on Instagram. The most horrendous bit to me is seeing their bodies tense up as they hit the floor. It's mad how willing they are to do it considering how blatantly stupid it is.
And thats coming from someone who played a game called Danger Can with his mates in his youth. It involved smashing a can of beer on your forehead and if it bursts you get down on one knee, neck it and then sing the line "my 13-month old baby" from 'Superstition' by Stevie Wonder for some reason. One time we considered upping it to Danger Keg which was going to be a 5L mini keg and a motorbike helmet but even we could see that it was a bad idea.
