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!
A greasy California kid, who thoroughly enjoys immersing himself in the realm of Muskratalia. This could include pooping your pants, getting piped up, wrestling with old men (in absence of old men, young boys are substituted), not cutting its hair, musky facial hair, constantly blacking out, claiming to be a vegetarian when it eats meat sandwiches, and getting piped down.
Ayooo that boy Musklon, or Marlowe the Muskrat, was being such a humpernickel last night when he blacked out and pooped his pants while reaching for that stringcheese.
An old, fat woman who's notorious for speaking her mind and giving people advice when it's least solicited; the kind who's usually president of the communityassociation, makes a lot of public complaints, and starts a lot of awareness and protest movements, because she has nothing better to do, often because she doesn't have a job and is nothing but a housewife with no post-secondary education or ambitions. Think about your neighbourhood busy-body; chances are that she's all but 1 or 2 of these things. (see: Kyle's mom)
A lot of times, she can also be a janitor at a school or department store.
Person 1: Look, here comes Humperdink.
Person 2: I hate that cunt.
Person 3: Me too.
Person 1: Let's look this way and just keep on talking.
Person 2, 3: Good idea.
