The condition experienced by a female after extreme sex causing her legs to respond as if the have no bones or were made of jello. This usually requires being plastered motionless on whatever object or surface the deed was administered. This syndrome often includes a deep mindless gaze at an imaginary object 30 miles away. These symptoms have been known to last for days after exposure to the magic stick.
