A word spawned from the NBC sitcom Scrubs. Bluncle is a contraction of black and uncle usually signifying when a black man becomes a "pseudo-uncle" to a white friend's child.
A term used to define someone who has surpassed the point required to be just a "wanker" or a "cunt".
Said person is in a league of their own when it comes to upsetting, offending, or hurting people either mentally or physically, thus requiring this insult too be hurled at them.
Person 1: "Did you see that man trip and mug that war veteran?"
Person 2: "Yes, what a Hoofwanking Bunglecunt."
