Guys, a few quick pointers here, and this isn't coming from a high five connoisseur, in fact it's not even coming from someone who partakes in regular high five pandemonium. But let's be honest, it shouldn't look this painful.
1. Don't close your eyes. Closing your eyes as if someone is about to give you a wedgie prevents you from seeing the other hand of the person you're trying to mimic that Bud Light moment with, leading to a wounded propeller motion from both parties involved, and the inevitable shower of pretzel bits thrown by those seated around you.
2. Don't flinch. From what we've observed, the slightest flinch can greatly alter the course of a high five and in some cases, throw you completely off balance, forcing those surrounding you into that compromising position of whether they should, a) help you regain your balance, or b) continue to enjoy your amusing downfall. Also, there's no reason whatsoever to flinch unless you sucked at dodge ball.
3. Don't flinch and close your eyes. This combination is what most would consider a complete disgrace. Unless there's a family of bats suddenly swooping through your row or that third sausage and peppers is angrily trying to squeeze it's way out after you let one go, there's really no excuse for it.
