To blow hot and cold is an idiomatic English expression that generally refers to a person who tends to be changeable in his opinions or mood. Phrases such this generally take on a different meaning than the definition of the words themselves. For example, the words hot and cold generally will be a reference to temperature. To say a person blows hot and cold, however, refers to his state of mind, his thoughts, or his temperament.

Many phrases like this are centuries old. Some have roots in stories or superstitions passed down from generation to generation. The phrase to blow hot and cold probably does not refer to a superstition or fear, but it is a very old expression that might have originated around 500 B.C..

When someone uses the expression to blow hot and cold in reference to another person, he is generally describing someone who frequently changes his mind.

An individual who blows hot and cold might also be prone to constant changes in mood. He might be exuberant and animated, then turn sullen and withdrawn the next day. He might show contentment and pleasure one day, then resentment or anger the next.

Blowing hot and cold can describe a person whose opinions on various matters constantly change. As an example, the person who fits this description may claim he's against the institution of public zoos. He might change his mind on this topic, however, and claim he believes holding wild animals in a zoo environment is a positive thing he supports completely. The following week he might say zoos have a negative impact and he doesn't believe they should exist. By faltering in his opinions, he could be perceived as blowing hot and cold.

Inconsistencies in a person's behavior and emotions can also be perceived as someone who blows hot and cold.

This person may be loving and committed one day, then distant and cold the next. He might be described as someone who is likely to blow hot and cold because of his changing emotional state.

I've noticed a lot of men will blow hot and cold when it comes to relationships. Sometimes they seem ready to marry their partner tomorrow, and other times they act like they want to break up as soon as possible. The decision to blow hot or blow cold seems to hinge on how well the relationship is going at that exact moment.

We used to say this about our restaurant manager for years. One day she'd come in and tell everyone to stop slacking off and do what we were getting paid to do. She'd go from station to station and bark out orders, then go into her office and slam the door. The next day, she would greet everybody with a smile, tell the staff they were doing a great job, and then sit in her office with the door open.

One time a new hire came up to me and asked about her. I told him she blows hot and cold. I said if she started criticizing him for little things, he should try to ignore it and wait another day. She'll probably forget she said anything negative. That was just the way she was- a very moody person.
