What a girl who has a boyfriend uses after you say “hey” to her online. the question mark indicates that she was being a rude bitch and wants to let you know that she’s bothered by the fact that you tried to be friendly with her.
Me: I found this cute girl on Facebook, I’ll say hey to her and maybe we can talk afterwards.
Me:(says hey to her)
Her: Hi?
how old are you, 5? you should know what this means.
person1: hi
person2: I don't want to talk to you.
You're a retard for not knowing what this means, FIND OUT YOURSELF DUMBASS...
