What does it mean when a girl says, "You're dangerous."?

[nihilynx]

I have had two girls tell me this, but I'm still not entirely sure what to make of the remark. They don't really say it in a flirtatious way, but rather a more serious/scared/intrigued way. One of them /seems/ to say it as if it's a good thing, while the other just seems to be implying that she can't relate to me or something. :/

Just speculating, though. Any ideas?

Some say it because they like bad boys, others say it because you seem like a bad boy and they'll be attracted to that, but don't want to be because they know it's bad for them
