V. To take the rest afforded by a suspension of voluntary bodily functions and the natural suspension, complete or partial, of consciousness; cease being awake. Or just a right way to say sleeping.

Pillowcasing

What you have to do in order to go bean bunging.

The act of getting your ballsack inside a vagina or butthole.
It's like when your pillow won't go in the pillow case so you gotta shove your whole arm inside the pillow case to pull the pillow in.

But obviously with your balls to get them inside the selected hole.

Omg Bobby is really bean bunging Janet right now. How long did it take him to get his balls in there?
I don't know, he's been pillowcasing her for awhile.
