koon luck

An unfortunate event or series of events where against all odds of a probable positive outcome, the worst possible outcome comes into fruition.

Be aware, Koon Luck feeds upon the unexpecting, the overly optimistic (despite previous cases of Koon Luck), the wishful thinkers, and doesn't seem to be prejudice of whom is impacted. Should you know someone with Koon Luck, distance yourself from them on all risky travel, business decisions, or financial advice as your life, personal health, or bank account will surely be anally raped by close proximity to their misfortunes.

Bob: "How in the hell did my thoroughbred horse get beaten by a three legged geriatric pony?"

Betty: "The only explanation is Koon Luck. Sorry for your loss Bob, now get the hell away from me you unlucky ass goblin."
