Berserk: violently or frenetically destructive; wildly destructive
To go berserk is to have a fit of destructive rage.
Berserk came into English from Old Norse. In Old Norse, a berserkr was a raging warrior. The Norse word is likely a combination of ber (bear) and serkr (shirt). A berserkr then was “a bearskin-clad warrior”.
Sir Walter Scott introduced the word to the English-speaking world in his book “The Pirate” published in 1822.
Synonyms include: mad, insane, crazy, demented, and deranged
“If you want to win anything – a race, your self, your life – you have to go a little berserk.” – George Sheehan
