Catapult: A "Catapult" move is a move where the attacker grabs the ring ropes and uses them to launch themselves at an opponent. I refer to this when the opponent is in front of you only.
Corkscrew : A corkscrew move is a move where the attacker spins their body prior to doing the move.
Corner: A move done in while the victim is in the corner. The Stinger Splash is a corner flying body press.
Crossface: A Crossface hold is usually added to submission holds. The attacker wraps one arm cross the face of the victim and pulls back. Chris Benoit is known for his crippler crossface.
Flying: Flying applies to any jumping move in game terms, but is tagged to anything that is not off ring ropes. I refer to this move as move being done Off the Top Rope also. The opponent is on the mat.
Handspring : The attacker performs a cartwheel prior to executing the move.
Moonsault: A move where the attacker applies a backflip onto the victim. The attacker is facing away from the victim when doing this.

Somersault: The attacker performs a forward flip prior to executing a move. 2 Cold Scorpio, John Kronus, and Juventud Guerrera are known for their Top Rope Somersault splashes.
Shooting Star: A shooting star is sort of a backwards moonsault and is in general only done off the top rope. The attacker is facing towards the victim. The attacker jumps and performs a back flip and lands on the victim. Jushin Lyger is known for first doing the Shooting Star Press (a facing towards the ring moonsault splash), however, Billy Kidman and Marc Mero have also used this as their finisher.
Slingshot : A "slingshot" move is a move where the attacker drops the victim on the ring ropes and uses the momentum as they "bounce" off to execute a move. Tully Blanchard's finisher was a slingshot suplex. It is also a spring off the ropes not facing opponent. One example is Ikuto Hidaka’s Slingshot Swinging DDT.
Springboard : The attacker leaps onto the ring ropes and springs off of them towards the victim. Rey Misterio Jr.'s finisher is a springboard hurricarana.
Standing Head Scissors : This is basically where you have someone in position for a piledriver. That is, the victim's head is placed between the legs of the attacker.
