What is what does it mean when someone blows in your ear?

Blowing in someone's ear is generally considered a playful or flirtatious gesture. It can be a gesture of affection or intimacy, and is often used as a way to demonstrate attraction or interest. It can also be used to playfully annoy or tease someone. However, it's important to note that not everyone enjoys having their ear blown in, so it's important to only do so with someone who is receptive to the gesture and has given consent.
