How it's used

Originally referring to livestock suffering from an epidemic, this term has evolved into a common insult for someone behaving erratically or irrationally. It carries a strong, aggressive tone and is often used to dismiss someone's behavior as nonsensical or mentally unstable. It is rarely used in a medical context today, as more precise terms exist for actual illnesses.

Examples

Why are you acting crazy, shouting for no reason?
He is always acting out of his mind, I don't know what he wants.

Common phrases

acting completely crazy and irrational

Common mistake

Do not use this word to describe actual medical conditions or viral outbreaks in a serious or professional setting, as it will sound highly offensive and derogatory. It is strictly a colloquial expression for criticizing behavior.
