Help from hot girls on this?

I go to the beach and hit on hot chicks in their bikinis all the time. But I've had 3 different honeys, 2 blonde chicks in high school and college brunette babe, all with unreal as*es that slapped the crap out of me and used the same move!!! They gasped, gave a cute look, shoved out their left hip and put their left hand on their hip and flipped their right hand out and slapped my face!!!! Then they called me a creep when I had my hand on my cheek cuz their right hand smack left their handprint on my cheek! I thought I was too fast though! I'm not when girls use this move. This move leaves me frozen with my mouth open so I CAN'T block this move! I don't know how to! This move sucks! It's impossible to figure out! I watched her cute look, hip out and hand on her hip, so wtf girls? Come on, a player needs your help against this move for real! Do any of you know it/had to use it? What's the trick to it? None of what I would do to block it works when bikini chicks use that move to humiliate guys! I even asked a few guys I know and 2 have had it used on them too and admitted they can't figure out how to block it either cuz they both got their faces slapped by it too!!!! Uuuugggggghhh, damnit!
