DONGBONE is English slang for the penis / todger / pecker / one-eyed-trouser-snake / wee willy weiner. The name probably springs from the often discussed (and false) belief that the human member contains a bone which allows it to become errect.
MINGER: Wow, look at that amazingly fit bird, I'm going to ask her to touch my dongbone!
AMAZINGLY FIT BIRD: I'd rather eat the scabs off a dead leper's back.
