The lowest of the low, a worthless member of some caste. A word to describe things that are pathetic, grundle should not be confused with the real word pronounced the same way, Grundel. Fuck Grundel.
"Georgia Tech is the grundle of the college world," or "Kenny is the grundle of the homeless world." Also a good candidate for overuse, if only to aggravate those around you.

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.
Dont grundle me, it hurts.

The area between the balls and the butthole of a male or female. More pleasurable area for the male, as it can also be referred to as the "underground penis."

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.
