How it's used

Originally referring to crossed telephone lines causing interference, this term has evolved into a common way to label someone as irrational or acting bizarrely. It carries a strong informal weight and can be offensive if used to describe someone with actual mental health struggles. Use it primarily for lighthearted teasing or expressing disbelief at someone's nonsensical actions.

Examples

Are you crazy? Why did you throw away my stuff?

Common mistake

Avoid using this to describe clinical mental health conditions, as it is derogatory and insensitive in those contexts. Stick to using it for erratic behavior or absurd ideas.
