Grundler

Slight spin-off of the creature Grendel from the epic poem Beowulf. Basically, a Grundler is the filthiest beast ever imaginable that lurks in your basement. The Grundler is actually an overweight man and has a rancid beard. The Grundler lurks in the shadows waiting for the opportunity to "bag-and-tag" a helpless victim.

1. The boy ventured into the dark basement to find his favorite toy when he was "sacked" by the Grundler and taken away to the Grundler's cave.

dirty grundler 

A Dirty Grundler is a certain kind of storyteller, known for telling tall tales and spreading false facts with a deadpan, straight-faced delivery, indistinguishable from if they had been completely serious and in earnest. A Dirty Grundler isn't a liar, per se - they aren't attempting to deceive anybody, just entertain.

B: Dude, Ray's a Dirty Grundler, there are no saltwater rivers in North America.

grundle 

Grundle 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 grundle?
A: You know, the chad, the part between balls and arse.
