grundle butter

A build up of sweat and unwashed buttcrack that results in a sticky, buttery poo-paste that may stain underwear or make it difficult to wipe successfully.

"Oh man, I keep wiping but there's just so much grundle butter! Maybe it's time to see a doctor..."

grundlemusk

Eau de taint said differently. Speaks to the aroma of the nether regions.

When returning underwear to a department store an associate exclaimed, "these can't be returned there is a strong grundlemusk!".

GrundleBundle

Essentially a Violent Tea-Bagging...

or my favourite turn of phrase "Like a dropkick, without the feet"

John gave Louise a hard grundlebundle last night, eye sockets full of testicals and a mouthful of anus, luckily only bruised her nose.

Grunday

A new day of the week on which to schedule your important meetings and have severe hangovers, the fact it doesn’t actually exist means it never really happened...

‘When should I schedule that important meeting?’.... ‘Definitely... Grunday’
