Only works if done while using the two key phrases: "mortal kombat" and "finish them/him/her".

Mortal Kombat (verb) :- To chain a succession of sexual finishers that run in a specific order:

1) A Donkey Punch
2) Angry Pirate
3) Spiderman
4) Strawberry Milkshake
5) Pearl Necklace
6) Frosty Hitler
7) Superman Punch

In essence, one is "finishing" one's opponent.
