Johnny Cage punch 

The act of doing the splits and punching someone in the groin. This was one of the original special moves of Mortal Kombat character Johnny Cage. If you are incapable of doing the splits, it is perfectly acceptable to kneel instead.

Guy: "Zork sucks!"
Me: (Does the splits and punches his groin) "Johnny Cage Punched!"
