A term used to describe a moment where someone does something beyond idiotic. The term is used because it describes the fact that only one sperm out of a million reaches the egg and the fact that this person's sperm just happened to be the one that fertilized it. ie: "One in a million, and you were the one who got in"
Friend decides its a good idea to jump on a trampoline while on a skateboard, then proceeds to slip off and break his leg and arm.
Me: One in a million dude, one in a million.
