Comes from the work armogeddon referring to stinky sweaty person of Armenian decent who denies the existence of deodorant. They can be quickly distinguished by their immense amount of hair, and sweat. They wear white t-shirts and tear off sweat pants with a lot of "bling bling" around their neck. They enjoy smoking stinking and being annoying.
Usually preceded by the word damn.
Damn Geddons are taking over this town.
