Imagine
You are at one of Bailey's shows. He searches the crowd for you and catches you staring at him in the crowd, so he gives you this look (see the picture above) once he finds you to make you laugh. If he hears you yell that you want to date him between songs, he will also give you this look. (You do this because you know that he can hear you and he knows that you are just joking around, 'cause you're already with him, lol)
I guess it's true that somethings are contagious, because you are known to give fans this same look, when they ask him about you, then ask him for his number during meet and greets, right in front of you. He handles it though, by nicely telling them that he's with you and he's happy with you.
