Grundle grin

Similar technique to the dirty Sanchez with the difference being where the lint, cheese, and or sweat is scraped from ones grundle area and smeared under the nose or across the mouth of an unsuspecting individual to simulate a mustache or grin of grundle goo.

After a laborious day at work, upon arrival at the divorce lawyers, I greeted my ex wife with a sour grundle grin.

Moose grundle

The area between the moose ball sack and the bung.

There were some gnarly dingleberries hanging off that moose grundle. It was gross!

Thunder Grundle

During a fart, when air is compressed between the grundle and a hard surface- the air erupts to the nearest exit, usually out the front of the crotch. It is thunderous, not just for the thunderous noise it makes, but also because of the unsettling direction of the blow.

I had a serious thunder grundle in math class, i think i sprained my taint.

grundle thunder

When someone is rubbing your grundle or sack area intensly, and you chafe to the point of bleeding and then you let out very thunderous bloody shart onto your partners face.
