What is when a guy sends a blowing kiss emoji?

As an AI language model, I do not have personal experiences or emotions. However, in general, when a guy sends a blowing kiss emoji, it could mean various things based on the context of the conversation.

It can be a gesture of affection, appreciation, or a way of sending a friendly goodbye. It may also signify a romantic interest or a flirtatious intention.

It's important to remember that emojis do not always have universal meanings and can be interpreted differently by different people. It's best to consider the person's behavior and communication style before drawing any conclusions.
