Someone else: So what's that thing sitting on your desk?
Me: It's a gonkulator, duh.

This is a part made for an 1967 austin cooper S in 1979 by me. It was used to keep the car engine cool as they were notorious for cracked heads and overheating. It consists of a gallon jug filled with water, a rubber 2' rubber hose connected to the top of the jug, a rubber hose from the jug to a copper tube with holes drilled at 1/2" spacing mounted in front of the radiator. You simply blew on the hose connected to the jug and water would be delivered in front of the radiator cooling it off just enough so that the car would not go into the red. Repairing the head made this item obsolete :) My twin brother came up with the name the first time we used it on a fishing trip.

In addition to the above definitions, Gonkulator is a band from Woburn, Massachusetts, who purport themselves to be the world's foremost farcical "black metal" band.

A big fan of the band introduced Gonkulator to several of his friends here in Davis, CA, and thus a strong following for Gonkulator was developed here.

None of us knew what Gonkulator actually meant before it became the name of the guitar effects pedal, so someone took the liberty to make the word mean whatever he wanted it to mean, and thus it became another synonym for vagina. I like it better than "pussy" myself.

From there, the verb "gonkulate" was spawned, and that is "to produce a secretion from the vagina or female ejaculate."
"Dude, don't go in that gonkulator without a raincoat unless you wanna catch something!"
