A day of death (either your own or somebody else's, metaphorically or literally). It can be said as part of trash talk or more fittingly as a war cry or victory cry.

The phrase is usually said without pronoun and is followed by a maniacal (although not hysterical) laugh. It is a reference to a non-intentionally hilarious scene in the shitty 1987 film 'Silent Night, Deadly Night II.'

The two states of being are as a human being, or a hungry ghost. Semi-regularly you need to ask yourself which you are. Sometimes it is human. Others, alas, it is hungry ghost.

The hungry ghost seeks validity outside of themselves. Someone pining for an indifferent ex is a hungry ghost. Someone who arrives alone at 6:30 on Saturday night to a pub is probably a hungry ghost. Obsessive checking of mobile phones, chat sites or networks are clear signs that one is a hungry ghost.

The best thing to do is just stay home and ride it out. Read a book. Find some good clean fun.

Scene from a crappy horror movie sequel called "Sillent Night, Deadly Night II." It is unintentionally hilarious because of poor acting and poor writing.

It has become a popular Internet meme, often featured in Youtube Poop videos.

Famous line from movie Silent Night, Deadly Night 2, in which the maniac killer randomly kills someone while they were taking out the garbage. Look it up on Youtube.

Also, it could be used to describe something that is completely terrible, negative, or unfortunate. Substitute for "Damn that sucks!"

The act of taking out a semi-automatic weapon of your choosing and shooting someone that's taking out the trash, while saying "GARBAGE DAY!"
