Nails = slut identifier.
The longer, the gaudier, etc. that a girl's nails are, the sluttier she is.
As with every rule, there are exceptions, but this seems to be the overall case. Seriously. It's weird. Or maybe this is common knowledge and I'm just catching on. And I don't just mean ultra gaudy nails = slut. I mean, even just a little extra attention paid to nails = sluttier.
Not in a bad way, really, just an observation.
I mean, I suppose it makes sense. The more effort put into your appearance, the more you're looking to get some attention... But the nails really seem to be an indicator, above anything else.
Feel free to call me names.
