Question: Information:  - Body piercing, a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewelry may be worn. The word piercing can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. Although the history of body piercing is obscured by popular misinformation and by a lack of scholarly reference, ample evidence exists to document that it has been practiced in various forms by both sexes since ancient times throughout the world.  - Body modification (or body alteration) is the deliberate altering of the human anatomy or human physical appearance. It is often done for aesthetics, sexual enhancement, rites of passage, religious beliefs, to display group membership or affiliation, to create body art, for shock value, and as self-expression, among other reasons. In its broadest definition it includes plastic surgery, socially acceptable decoration ("e.g.", common ear piercing in many societies), and religious rites of passage (e.g., circumcision in a number of cultures), as well as the modern primitive movement.  - Genital piercing is a form of body piercing. It involves piercing a part of the genitalia, thus creating a suitable place for wearing different types of jewellery. Nevertheless, the term may also be used "pars pro toto" to indicate all body piercings in the area of anus, perineum, genitals and mons pubis, including piercings such as anal, guiche, and pubic that do not involve perforation of genitalia. Genital piercings can be done in men or women, with various forms of piercings available. The main motive for both genders is beautification and individualization, in addition some piercings enhance sexual pleasure by increasing stimulation.  - A portmanteau (; plural "portmanteaus" or "portmanteaux" ) or portmanteau word is a linguistic blend of words, in which parts of multiple words or their phones (sounds) are combined into a new word.  as in "smog", coined by blending "smoke" and "fog", or "popportunity", from "popping" and "opportunity", or "motel", from "motor" and "hotel". In linguistics, a portmanteau is defined as a single morph that represents two or more morphemes.  - A frenulum piercing is a type of body piercing located on the underside of the shaft of the penis . A series of parallel frenulum piercings is known as a frenum ladder . A frenum ladder may be extended to include lorum piercings , hafada piercings and guiche piercings .  - A lorum is a male genital piercing, placed horizontally on the underside of the penis at its base, where the penis meets the scrotum. The word "lorum" is a portmanteau of the words "low" and "frenum", so named because it is essentially a very low-placed frenum piercing. Much like the frenum piercing the lorum can have multiple rungs added and be a ladder as well.
