Any girls in high school that know?

if you know this, you gotta help me. this adorable chick, she slapped my face. she's a sophomore, and i don't know how she did this, must just be some move girls in high school know how to use against us, i don't know it. she stared right at me, but then she scrunched up her face and was like hmmph! right then, she pushed her hip out while she stood, but at the same time had her hand on her hip(the one she pushed out to the side)?? i saw all that, but next she flips out her opposite hand and slapped my face!!!!! i was frozen by that, wtf??? how do you block that, i can't!!!! a lot of babes in high school know how to use that move??? arrgh, sh*t! HELP ME AGAINST THAT! do i look at the look at her face? or pay attention to the hip when she pushes it out? or look at her hand she has on her hip? that move is too confusing!!!!
