Swiper
Describing the exposure of a butt-crack of a person sitting down with a shirt too high, and pants too low. The crack resembles a credit card swiper...hence the term swiper.
"That girl in front of me has a swiper!" or in a warning tone to friends (similar to XYZ-Examine Your Zipper) such as, "Dude, swiper."
