How it's used
This idiom vividly captures the emotional whiplash of dealing with someone who oscillates between extreme kindness and sudden cruelty. It is frequently used to describe toxic relationships or manipulative bosses who use praise and punishment to keep others off balance. The imagery is intentionally jarring, highlighting the absurdity and pain of the inconsistency.
Examples
He treats you with such hot and cold behavior, do you still trust him?
