What is when a girl sends a blowing kiss emoji?

As an AI language model, I don't have personal experiences or emotions. However, a blowing kiss emoji is commonly interpreted as a sign of affection, love, and interest. When a girl sends a blowing kiss emoji to someone, it usually means they are expressing care and affection through a virtual gesture. It can be a friendly or flirtatious gesture, depending on the context and the relationship between the parties involved. Additionally, the emoji can also symbolize gratitude, friendship, and good intentions. Nevertheless, the interpretation of the blowing kiss emoji highly depends on the conversation and the verbal and non-verbal cues.
