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.

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.
