Grundle

The grundle is not simply just the area between the testes, and the anus, rather it's the wormlike skin line.

My grundle looks eerily similar to the scare on Madeline's stomach.

Grundlesac

The flap of skin, in males, between the scrotum and the anus, which can be used for various things such as clipping flashing lights to. Grundlesac's can vary in size from droopy to so small that they can barely be noticed.

Damn Alex, that is so sweet how you can clip that pulsing belly button ring to your giant grundlesac.

After eating at the Harris Millis Dining hall at UVM, the rumble in your stomach, followed by feeling nauseous. Can include grundle shits the next day.

Grundle days

The Grundle is the narrow area between a man's ball-sack and his anus.

The "Grundle Days" are those few days which fall between the end of Christmas Day and the morning of New Year's Eve.

What are you doing with the Grundle Days this year?

Nothing.

Me too.
