The grundle, according to my Columbus, OH elementary school upbringing, refers not only to the unisex taint, but can also refer to the mythical "sideways" vagina. I think of this rare sort of grundle as the feminine counterpart to the maverick male "chode." If anyone ever sees a babe-a-rino with a honest-to-God grundle perched atop her burger, shoot me a comment.
AAAH!!! That bitch has a grundle that looks like a Venus Fly Trap, dudes.

The word Grundle for most people means between youre scrotum and youre asshole, but it also is used as a verb. It means to stick 2 fingers in between the scrotum and the asshole.
