I talked about de volada in another post, which you can find here. However, when you combine de volada with andar, you get a completely different meaning.
Speaking of andar, if you're not familiar with that verb, you can read about it here.
But let's move on and start talking about andar de volada.
Esta chava anda de volada conmigo pero no le gusta.
This girl is flirting with me but I'm not attracted to her.
¿Quien es esa chica que anda de volada contigo?
Who is that girl flirting with you?
Another way to talk about flirting is using the verb coquetear, which also means to flirt. I wrote a little about coquetear here in a previous post. That post is a little long, so if you're short on time, just jump to the end of the post to get directly to the stuff on coquetear.
That's it for now. Sooner or later you're bound to overhear someone talking about flirting, or perhaps you'll anda de volada con alguien yourself.
