When a girl sits on a guy's penis (so that his penis is up her butthole), she starts spinning in circles while she is still on him. During this, the guy starts moaning sounds similiar to those made by an electric pencil sharpener.
Friend : Hillel, did you and Beverly do the pencil sharpener?

Hillel : Why, yes! We did do some pencil sharpening of our own. I also got the moaning sounds down perfect, Zzzrrrrrr Zrrrrrrmmm

Friend : Thats great, maybe Beverly will pencil sharpen me too!
