The part of the body between the skin flute and vegemite valley. In men this part of the body is usually hairy and sweats quite profusely. In some cases the grundle is also known to be the source of many dags (faeces mixed with hair)

The entirety of one's package and asshole, to inlcude either to cock, balls, taint, and asshole, or vagina, taint, and asshole. One's grundle often bears the brunt of the day's heat and is most likely sweaty and horrific smelling.
1) I took my undies off and holy shit did my Grundle smell like rotten cottage cheese!

2) I'd love to punch that dude right in his Grundle

3) I heard it's very easy to get into her Grundle.
