The patch of hair between your balls and asshole (the grundel) and when it gets too long, it looks strikingly like a mohawk.

"Yo Jimmy, give me a couple minutes, I have to go trim my Grundel Hawk because I am expecting a rim job from Wendy tonight."

"I need to shampoo my Grundel Hawk, that shit just stinks."

grundle grunt 

n.
1. An STI.
2. The common name given to lice that inhabit the area known as the grundle or taint. Grundle grunts are usually contracted from illicit sexual behavior or walking around the woods naked.

Grundle grunts are also known as "taint tics", "scrotum skippers" or just crabs. When contracted elsewhere, grundle grunts are named after the area contracted. i.e. pubic lice, chin climbers, nipple nabbers, happy trail hikers, or earwig waggers.

Ouch! That grundle grunt is very friendly.
