A small-sized fatality

[HelloHound]

So I'm trying to figure out a scene I want to do where my protagonist is lifted by the collar of her shirt and it ends with her swinging her lower body up and using her legs to snap the assailant's neck.
Now I think that scene is sick as hell so even if it is literally impossible by all laws of physics I'm still including it because I'm not getting paid to write and there are way stupider things out there.
But! I care a little about the braincells of my viewers and would like to have it as reasonable as possible for a small girl with super strength lifted by her neck to maneuver to snap the neck of an adult man so I am asking for the infinite wisdom of the forum

How strong? Rather than snap, why not a straight upper kick to under the jaw that snaps the neck back so hard that the guy gets ded? Or she swings her legs around the guys arms causing an arm bar situation that she then uses to swing behind the guy and snaps his neck from behind on his shoulders? Or the guy brings her really close to his face to yell or kiss her and she kicks her left leg to wrap around the back of the guys neck (like he’s about to snack on her lunch box) while kicking out with her other leg to generate torque to cause the guy to flip over and he lands on the side of his head/neck that causes the guy to get ded from the neck breaking? Or she swings her one leg around the back of his neck again and just squeezes her thigh and calf together so hard that it causes his neck to snap while she’s using his arm to support her body still? ….or just go all the way in with the suspension of disbelief and have her wrap both legs around the guy, break his arm hold, clasp his arm in hers and swing her hips/flex her hips and upper body in way that would cause people to spin and it twirls the a-hole into a spin while she squeezes her legs and snaps his neck!

You'd have to give me the play-by-play, cause I'm having trouble visualizing how someone's neck gets snapped if they're lingering in the air.

Perhaps they pull some sort of Black Widow-type shit and twist around the assailant's arm, grapples onto their neck with their legsthen slams them to the ground. And finally, once they're pinned the protagonist cracks them with their thighs?

That's how I would write it.

That ^ but like... She was in the air, it would be believable with someone who has decent strength and mobility to maneuver themselves while still in someone's grasp.
