A state of wild rage or frenzy.

{"Origin":"The word 'berserk' originates from the Old Norse 'berserkr,' which referred to Norse warriors who were said to fight in a trance-like fury.","Historical and Cultural Context":"Berserkers were legendary Norse warriors who were thought to have fought with an uncontrollable ferocity, often attributed to a trance or possession by a spirit. These warriors were believed to wear bear skins, which is reflected in the name: 'ber' meaning 'bear' and 'serkr' meaning 'shirt' or 'coat.'","Evolution":"The term was adopted into English in the early 19th century, initially referring to the Norse warriors themselves. Over time, it evolved to describe anyone exhibiting wild or frenzied behavior.","Modern Relevance":"Today, 'berserk' is commonly used in English to describe someone acting in a wild or out-of-control manner, often in a humorous or exaggerated context."}

Berserkers are often depicted in Norse mythology and sagas as being immune to pain and capable of extraordinary feats of strength during battle.
