Drop Shadow

When a woman shows her nipples in a way that doesn't violate a social medias terms and policies. To be done correctly she will wear a thin, white or light colored, cami with no bra so that you can see the contrast of the areolas and nips. If lucky you may catch a glimpse of the secretive and often debated areola 51.

"Hey, did you see that picture of Jessica on Facebook?"

"Yeah bro, she went heavy on the drop shadow."
