Formal regions are different from functional regions because functional regions often have a focal point, such as a city, that is the center of the region, and the rest of the region is built around that focal point. Examples of functional regions include New York City and Los Angeles. Vernacular regions are developed by ordinary people, often based on their language. Vernacular regions include the American Midwest and South, the Swiss Alps and southern California.
Side Lip Piercing. A side lip piercing is a labret piercing placed towards the left or right side of the lip. The term side lip piercing usually refers to piercings on the lower lip - upper side lip piercings are called Madonna or Monroe piercings.
A navel (belly button) piercing passes through the rim of the navel. While they are typically done just above the navel on the top ridge, they can also go anywhere around the outside of the navel, wherever there is a fold or lip.. This type of piercing is fairly common, particularly among women.
