When fucking a girl from behind, right before you cum you pull out, yell "FINISH HER!", stick it in her ass, and bust a load.

The art of first embarrassing, then finishing off the one you're fucking, after you first have already ejaculated.
Only works if done while using the two key phrases: "mortal kombat" and "finish them/him/her".

To have your heart ripped out, Kano from Mortal Kombat styles by someone you have a crush on/love

When you take a shit that is so devastating and foul that right before you flush you hear Shang Tsung say "Finish him!"

During intercourse right as you bust your nut you scream "FINISH HER!!!" and put a rag soaked in chloroform on their face. Your friend who has been hiding in the closet proceeds to finish her.
