The female gluteal fold that shows itself when wearing a pair of fine ass jorts. (Underass equivalent of the underboob).

Get the shelfmug. A common photography pose in which a person places their hand beneath their chin, forming a sort of shelf for their head to rest on, in order to better frame their face. When such a pose is used for a selfie, the resulting image is called a "shelfie"
