From chainsaw-wielding killers to bloodthirsty zombies, berserk is the perfect term to describe the villains of most scary movies. The term originates from Old Norse, a language that evolved from ancient Viking tongues, with bjorn meaning "bear" and serkr meaning "shirt" or "armor." With this etymology in mind, when someone goes berserk, it's as though they've covered up their rational human behavior with the wild aspect of a bear. thanatopsis Do you spend a lot of time in graveyards?

Poet William Cullen Bryant first popularized the style with a poem called—you guessed it—Thanatopsis. perdition In Christian tradition, perdition is the state of final spiritual ruin or eternal damnation to which the wicked are condemned.
