This move is often erroneously described as a moonsault ura-nage slam. To perform it, an attacking wrestler stands slightly behind and facing the side of a standing opponent. The wrestler then reaches under the near arm of the opponent, across the chest of the opponent and under their far arm, while placing their other hand on the back of the opponent to hold them in place. The wrestler then performs a backwards somersault (moonsault) while holding the victim, driving the opponent into the mat back-first. This move can also be performed off the top rope and is known as a moonsault side slam or "solo Spanish fly" in reference to the Spanish fly double team move. The move was used by Paul Burchill and John Morrison, both of whom called the move "C-4". A famous user of the Move is Will Ospreay, calling it the "Rainham Maker. Current WWE wrestler Charlotte Flair also uses this move."
