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.

Get the Grundlemug. Grundle. North Leicestershire/ South Derbyshire. (N Vb) To feel the urge for a shit, or to contract the belly muscles to hold it back. Eg: I'm grundling a dump back. Or, I've got such a grundle, i need your lav, or I'm grundling a fart - oh, sorry, that's rank. The pressure on the 'area'.
