The idiom "go berserk" means to become extremely angry or out of control, often in a violent way. It is used to describe someone who loses their temper and behaves in an irrational or dangerous manner.
The origin of the phrase comes from the Old Norse word "berserkr," which referred to a warrior who fought with uncontrollable rage and ferocity.
You can use this idiom in various situations where someone loses their temper and behaves in an irrational or dangerous way. For example, you might say, "He went berserk when he found out he didn't get the job," or "The crowd went berserk when their team won the championship."
It's important to note that "going berserk" is not a positive or desirable behavior, and it's important to control your emotions and reactions in a safe and appropriate manner.
