Brodinger's Cunt

A cock experiment, sometimes described as a paradox, in which a semi erect penis is inserted in the direction of female genitalia, but for whatever reason it cannot be determined whether the penis has actually entered the vagina, or whether it is merely wedged between the purgatory that is the butt cheek - vagina junction. Until it is observed, the penetration is both occurring and not occurring at the same time, a state commonly referred to as cocktum superposition.
