grundlecunt

The grundle of a man so morbidly obese, so overcome with ass flaps and rolls that it contains a depth similar to that of a vagina.

I thought I had slipped deep into Fat Steve's rectum, but when my cock fell between his legs after the first few thrusts, I realized that I was merely penetrating his hairy grundlecunt.

Grundlebug

tiny pieces of feces that you miss wiping after you go the toilet, that dry and become attached to your grundle hairs. Also known as "dags", the removal of these items is often met with a severe stinging sensation and repulsive odour stain on the fingers

1. "just like ripping off a band-aid, i closed my eyes and yanked off the grundlebugs until they were all gone and it stung like crazy!"

Grundleplith

A grundleplith is the foreskin that has been recently removed and set out to dry on the lab table from a circumcision. One may act as if they are a grundleplith by being a complete douche and shitting on everyone's day.

Justin Bieber was nominated as Grundleplith of the Year 3 years in a row.

Grundleburst

An awesome band. They rose to fame with they're number 1 hit song, "2 Cool 4 School". Their songs are generally recorded in one take around a single mic, and often improvised (though sometimes based off of snippets of magnetic poetry. The members are as follows:

Mick Furgn: Vocals
Nick Schweinstegger: Guitar, backup vocals
Max Sven III: Kazoo

Their first album, released in 2006, was called Imagine Shlock, and was recorded on two non-consecutive afternoons.

I just listened to Grundleburst's debut album Imagine Shlock and it was so good.
