"NOW do you want to wrestle?" ...and she
squeezes until Jo says,
"Let Go!"
Angie replies,
"YOU let go first!"
Etc...
...and voila, we have a clear evolution into
Female Submission Wrestling

In frustration Angie slaps at Jo's butt, so Jo slaps back...
...until Angie scores a hard smack
on Jo's butt with a loud
"WHAP"!! (see next frame for Jo's reaction)...

Here Angie's hand is recoiling from the slap.
After this
stinging slap,
Jo vows
"As soon as I get up your gonna GET it!"GIRLFIGHT!!
