Talked to a girl and then she moved her tongue out of her mouth to the side. What the heck?

^Is this a sign that she finds me "yuck" or something?

I was at work and just said "hello" to this random girl to talk to in our break room as she was new at our work center. She then turns to me and then just throws her tongue out of her mouth and to the side while looking at me as I am leaving to go back to work. Good, bad, or whatever sign?
