Grundlesburg 

A little Parish between Pussyborough and Asscrackerton inhabited mostly by VERY unsavory characters.

I blew a deal on the way South and hooked up with a blue crab in Grundlesburg. Shitty scene man.

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!"

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.
