Do girls say "Hey, You!" to be flirty?

WARNING: Potential stupid question, but please, cut me some slack! ;)

Like when a girl is getting to know you better and she greets you "Hey, You" (calling you "You" instead of your name). And she definitely knows my name because she calls me by it sometimes. But recently we've been talking a lot more and becoming closer, and I noticed she says this to me in person and in texts. I know it could mean absolutely nothing...but do girls often use this when they are flirting, or if they are interested?
