I have no idea, to be honest at this point I basically call everything a whatever these days, but according to your definition maybe that just means I'm ahead of the times (your definition actually gives me hope there that perhaps I'm not just fried or fucking stupid).
You know a whatever I never really knew the real name for, it's the one Daewon does a lot but a good example is at 7:59 in this:
I remember the Grind Session game on the PlayStation called it the 'slamma jamma', but I swear I've heard it called a few other things. Matt Hensley also used to do similar tricks off jump ramps with funny names I keep hearing and then forgetting because I personally always sucked at jump ramps.
Little kid in me actually always wanted to do the slamma jamma thing at least once to experience how it feels, since I first saw a clip. It just looks so funny and more accessible than a McTwist so maybe it can be my personal McTwist? Except it took me two decades to even start registering how that move worked. To this day I haven't tried it once. But I'm starting to read it as basically a (strong) stretch on the beanplant. Maybe one day I'll try it over a hip and slam on my ass.
