Stupid Fad of the Day: Smacking Friends in the Face

According to the latest senseless video fad from Vine, sadistic kids are smacking their unsuspecting friends in the face just to capture a video of their surprised, terrified and even tearful reactions. Uploaded with the hashtag #SmackCam, many of these videos feature half-witted bros hitting girls in the head for their amusement, like this Vine of a dude bashing a young woman's head in with a jug so hard that it bursts. All stupidity and safety concerns asides, didn't the MTV Jackass crew already beat this horse to death many years ago?
