The adjective comes from the noun berserker, or berserk, which is from the Old Norse word berserkr, “a wild warrior or champion”. Such warriors wore hides of bears, which explains the probable origin of berserkr as a compound of bera, “bear” and serkr, “shirt, coat”.

These berserkers became frenzied in battle, howling like animals, foaming at the mouth, and biting the edges of their iron shields.

The term berserker was first recorded in English in the early 19th century, long after these wild warriors ceased to exist.

Old Berserker (Bear Skin) was a famous character in Norse mythology who was a supernatural warrior who fought with great fury and feared nothing. It is said that he even fought without weapons or armor and rushed into battle “protected” only by the bear skin thrown over his shoulder and clawing and biting his victims to death.

Examples of modern berserkers minus the bear skins

Based on this myth, any fierce figher was soon called a berserker; especially one who fought with a fury that seemed almost insane and terrified even his allies. In time, to go berserk came to mean the violent, furious rage of a madman.

Modern berserkers gone wild.

Back in 1995, there was an article about three young men, sixteen, seventeen, and eighteen years of age; two of whom were arrested for killing their parents.

The brothers are charged with three counts each of homicide and conspiracy to commit homicide in the slayings of their parents and their younger brother.

Police say the brothers had threatened for years to kill their parents as revenge for trying to impose their strict way of life as Jehovah’s Witnesses on the boys.

The three, two brothers and a cousin, all had shaven heads and tattoos. One had “Sieg Heil!” tattooed above his eyebrows, while two of them had “Berserker” tattooed on their foreheads; an apparent reference to Norse folk stories about warriors so fierce they needed no armor.
