Split-Legged Moonsault
From Luchawiki

A type of corner moonsault wherein the attacker employs the Arabian Press technique of bouncing with their lower legs instead of their feet. Albeit - because it is in the corner on two perpendicular ropes - they must split the legs instead of keeping them parallel.
Can be further enhanced with techniques like the corkscrew, as used by La Sombra, Brillante Jr., and Johnny Mundo (who christened it Starship Pain).
