grundle butter

An unfortunate gelatinous sweaty buildup on the grundle (which is the hair and area between your genitals and arse-hole).

I pulled off my jock and found a pat of grundle butter on it.

Grundle Bears

A treat where you take perfectly good Gummie Bears and wipe them all up the anus region as if they were toilet paper.
In order for it to work well, there should not be poop stains on any, or the camp counselors might notice. Just the fact they've been up in there is nasty enough, trust me.

At a percussion camp, our school's drumline make a huge Ziploc bag of Grundle Bears that the college counselors snacked down. Yummy.

grundle scum

the crusty and flaky substance that forms between a persons ball sack and butt hole. The substance often secretes a foul smelling odor. In some cultures it is a symbol of dominance for a male to force a female to eat the scum off of the male. This has also become a popular act in College dorms throughout the United States.

Hey fuck face, every time you sit on the couch naked you leave a pile of grundle scum.
