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 community association, 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.
A word with great power. Can be used in many circumstances. The humperdinks are led by Abu nutty and the nextnumber 1 humperdink will fulfill the prophecy.
