Most Helpful Guy
I wouldn't really care, to be honest.
If I noticed, at all, I'd probably just think to myself, "Huh, either she's trying to show off, or she just doesn't care," and then get on with my life. Wouldn't even give it a second thought.
I'm an ass man, in that I find them attractive, on the right girl, but a random crack, from a girl whom I don't know, is neither attractive, nor unattractive. It just doesn't do anything for me.
