Grundle Secretion

The scientific term for suffering from inordinate amount of sweat and wetness located around one's grundle. This nether-region, tucked between one's balls (or vagina) and anus, shows symptoms of Grundle Secretion (GS) due to any physical activity, sweating off the booze from a hangover, sitting in a chair that increases grundle temperature above the grundolgist-recommended 100.3 degrees Fahrenheit, among many others.

John: "Dude, when Megan and I switched airline seats I didn't think I would be sitting in a damp puddle. Do you think she peed?"

Grundologist Greg: "No John, she did not. She, along with 41% of other Americans, suffer from Grundle Secretion. That was just a mixture of her grundle butter. Airline seats often contribute to excessive GS."

Grundle

1. The hairy sector separating your bunghole from your dilly-dally.

2. A room in a house/apartment specifically for men to hang out at, also referred to as a "man cave".

After a long, hard day of working in the yard, I love to come inside and scratch my sweaty grundle.

Man 1: Dude we've got the Nintendo 64 all hooked up in the grundle! Come over!
Man 2: Cool, bro! I'll bring over some PBR and an extra controller!
