There's this girl I like that goes to karate with me. She's 14 years old and im 16 and she sticks out her tong?

She sticks out her tongue? Does anyone know what that is supposed to mean? Does she want me to kiss her? Does she want to kiss me? Does she want to make out with me? Or is she just flat out teasing me?|||It means she's proly 9 not 14....
