That's what cervical dislocation is. The cervix is the neck. You're dislocating the head from the body, via the neck.

AFAICT, biologists didn't screw up and give two different body parts the same name. Neck bones are called cervical vertebrae.

I see where you're going with that. The other body part is also a narrow passageway, which in many contexts is called a neck or bottleneck. In my language, we call that other body part "The neck of the womb" צוואר הרחם.

If you properly dislocate it (thus severing the nerve) it doesn't even get to twitch. In theory it's slightly cleaner and better even for the chicken.

It does require a bit of technique though, and the consequences of not doing it right at first can be very upsetting.
