dingleberry grove
The portion of the human body located between the sex organs and the anus; the perineum. Also commonly known as the taint. So named because the coarse pubic hairs that grow in this area tend to collect and hold onto clumped bits of toilet tissue and human excrement (known as a dingleberry), much like fruit growing on a bush.
You're not getting into bed until you hit the shower and wash those crumbs outta your dingleberry grove...I ain't doing an extra load of laundry in the morning!
