Grundlepuss 

A pet name for humans usually in intimate relationships where silly word play is the number one kink that binds them together. It is a deep word and should ration it.

grundlemusk 

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

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.

Grundlebutter 

The butter from built up cheese in a warm crevous.

GrundleButter Keelhaul 

A hazing ritual or punishment in which an unlucky fellow is strapped to a pole or board, and with the help of many assistants is moved back and forth under an obese unwashed man's undercarriage, from the top of the crack to the back of the sack, in a wiping or scrubbing motion until dead or unconscious.

"Greg informed us that Revenge of the Sith is his least favorite Star Wars film, so I petition that his punishment will be a GrundleButter Keelhaul."
