INDIANAPOLIS — It's time to wind those backhands up to celebrate National Slap Your Coworker Day! (I'm not smiling; you are). So, if you've got a coworker who's been working your last nerve, here's your chance to give them a good whack, according to National Today. Though the so-called holiday might not save you from your Human Resources Department - or the police, for that matter. To get the perfect slap technique be sure to have a flat, open-handed strike on the palm side of your hand with both feet planted, according to the rules of the Power Slap competition. The striker must not hit the eyes, ears, mouth, or temples.
