grundelberry 

The wicked stepsister of the dingleberry. Formed when one has diarreah or other digestive ailment, the grundelberry is a vulgar clump of human excrement that forms in small balls around hairs found in the human grundle.

Ex. When one goes to Taco Bell and eats three 1/2 lb Beef Combo Burritos, one will experiance gastro-intestinal defiance leading to grundelberry infestation of the grundel.

Dis-Grundeled 

1. To be so pissed off and stressed about something as to force a strain or tear of the grundle.

2. To hit someone with such force (see: dial-tone)as to seperate the grundle from the rest or the sphinctal area.

1. When I found a wad of sticky singles in my girlfriend's panties it left me severely dis-grundled.

2. When Yackl outdraws me after going all-in with a Jack-Two offsuit it makes me want to dis-grundle him.

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.

A: Ray told me this is the longest saltwater river in North America!
B: Dude, Ray's a Dirty Grundler, there are no saltwater rivers in North America.
