I think people feel spray-on tans aren't classy, but then, I don't think tanning booths are all that classy either. I would rather spray dye on my skin than pay for cancer.
Because of the weather (I live in Washington state) the sorority girls are my university are always fake-'n-baked, and they put stickers on so that afterward, there's a white playboy bunny or dolphin or heart surrounded by crispy tan.
...Yeah, definitely NOT classy.
