look up any word, like fleek:
An old boys summer camp favorite, the Wibble. The act of putting your own hand down your pants, holding your balls until your hand is nicely warmed, then placing your clammy palm on the unsuspecting cheek of a fellow camper or counselor while exclaiming "Wibble".
Johnny removes his sticky warm palm from his pants and plants it on the cheek of his unsuspecting counceller Bill:

Johnny: "Wibble!!!"
Bill: "Sheeeet, wibbled for the 4th time today..."

Wibble can mean anything from a hammer to a ham and musterd buttie.
While working on site with a mate off 8 years we used the word wibble to mean anything.My mate could be about to cut a length of timber he might say pass the wibble and I would pass him the saw.I might be about to fit a door and would say pass the wibble and he would give me the plane.We had worked together for so long we instinctivly knew what wibble was needed.
