"Is Big Show a face or heel tonight?"
"Alicia Fox is a heel. Update your cards."
Superposition is a concept in quantum physics which states that because it's so difficult to measure "where" subatomic particles might be at any given time, they are "everywhere at once," and measuring them at single point imposes a limitation to just one possibility.
The Big Show-Alicia Fox Superposition states that because both wrestlers have experienced frequent allegiance changes between face/hero and heel/villain, assuming they are one or the other limits them to just one possibility - when they are all possibilities at any given time.
