Grundle Surfing

When you're having sex with a girl and you pop out, but try to get back in without using your hands, resulting in sliding on her grundle continuously, or surfing.

Man, I was fucking her and slipped out, but I was too lazy to use my hands so I was just grundle surfing for a bit until I got it back in.

grundle grease

An oily sebaceous substance secreted from peri-anal musk glands to lubricate the grundle and attract females.Turns rancid in a matter of days but is essential for fluid walking motion in that it reduces the friction between the butt cheeks.

I need a shower. My grundle grease has gone sour.

Grundle Leech

A sexual deviant that suffers from a taint fetish and when engaged in sexual activity, latches hold and spends an inordinate amount of time stimulating the grundle area of their partner.

I'm not going out with Carl again. All I wanted was a little oral action when we got home and he turned out to be a Grundle Leech.
