The New and Improved High-5

I learned how to do two spin offs of the regular high-5 this weekend.
For the first one, you tell someone to give you a high-5. Then, when they're about to hit your hand, you ball your fingers up into a fist, except for your thumb, and they end up hitting the pinky end of your fist. You're then obliged to shout, "turkey!"
I'm pretty sure for the second one, both participants in the high-5 need to know what's happening. Otherwise, both will just end up looking like a major goober. For this one, both high-5ers begin, acting like a normal high-5. Then, as the hands are about to slap together, they both curl their fingers, and retract their hands in a wave-like motion. This one is called the jellyfish!!
