Quick answer: “Blow Hot and Cold” means keep changing your opinion or attitude about something.

Quick Definition

Blow hot and cold — to keep changing one's opinion, feelings, or attitude about something or someone; to alternate between enthusiasm and disinterest.

Origin & History

This idiom traces back to one of Aesop's Fables, "The Man and the Satyr", in which a satyr sees a man blow on his cold hands to warm them and later blow on his hot soup to cool it. The satyr, confused by the man's contradictory actions, refuses to associate with someone who "blows hot and cold from the same mouth." The fable was widely known in ancient Greece and Rome, and the phrase entered English by at least the 16th century.

The idiom is used today to describe inconsistency in opinions, feelings, or decisions — particularly in professional or romantic contexts. It often implies that the inconsistency is frustrating to others. Learners who want to check other figurative expressions can consult general reference works such as the Cambridge Dictionary, which document how such idioms are used today.
