From the game Zelda Ocarina Of Time. There is an enemy called the redeads. Some sort of undead people who when you get too close they scream and jump on your face, and practically hump you. Thus they are Humperdinkers
Alex:So yeah I was playing Zelda last night,and I just turned into an adult.
Steve:Oh yeah adult link is pretty dope
Alex:Yeah its alright....
Steve:Is something the matter?
Alex:Well after becoming an adult I entered the market, and there were all these zombie like creatures. So I approached one to make small talk and the next thing I know the damn Humperdinker clung to my face and violated me!
