How it's used
Originally describing a telephone line fault where signals crossed, this term evolved into a common, informal way to call someone irrational or erratic. It carries a strong sense of disbelief or frustration and is frequently used in casual arguments or when reacting to someone's bizarre behavior. While it is very common, it remains a blunt insult that should be avoided in professional or formal settings.

Common mistake
Avoid using this to describe someone with a genuine clinical mental health condition, as it is strictly a colloquial insult for irrational behavior or poor decision making. It is not a medical term and can be offensive if directed at someone suffering from actual illness.
