grundel 

Grundel is another word for chad: the region between the balls and the arse-hole; can be an erogenous zone for some.

Girl: I was fingering that part between his balls and his arse and there was shit there.
Everyone listening remained silent but later laughed among themselves:
'Eww! He had a shitty chad.'

When you measure your dick, you don't start at the arse-hole and include the chad; you risk getting shit on your measuring tape.

Q: What on earth is a grundel?
A: You know, the chad, the part between balls and arse.

Grunfest 

Its a holiday on the second Sunday of June. Its when men decorate there Grunskins with paint and glitter in honor of that body part. In tradition a man is suppose to have a woman lick it 14 times before painting.

I have been to 5 circle jerks, to goat ropes, but never a grunfest.

Grunge pump
