The bum or butt flap is a piece of removable material that hangs from the waist to cover the rear end. The flap is of ambiguous origin, but probably was originally intended to reduce abrasive wear to pants. Pavement can rapidly wear the seat of pants, and flaps act as replaceable buffer material. They also provide some protection from damp or cold surfaces. The freely swinging flap dries faster than wet pants, and can be easier to clean. Bum flaps are often worn as a superfluous fashion statement, usually emblazoned with punk iconography.
Flaps are usually constructed by hand with the most suitable material available, often canvas or denim of discarded clothing. Water resistant and thermally insulating flaps are desirable for long distance rail travel and camping. Flaps may be stitched to clothing, or suspended from the belt. Punks (crust punks) have been known to wear these

Flap surgery is a technique in plastic and reconstructive surgery where any type of tissue is lifted from a donor site and moved to a recipient site with an intact blood supply. This is similar to but different from a graft, which does not have an intact blood supply and therefore relies on growth of new blood vessels. This is done to fill a defect such as a wound resulting from injury or surgery when the remaining tissue is unable to support a graft, or to rebuild more complex anatomic structures such as breast or jaw.
The skin can be divided into 3 main layers including the epidermis, the dermis, and the subcutaneous tissue. Blood is supplied to the skin mainly by two networks of blood vessels. The deep network lies between the dermis and the subcutaneous tissue, while the shallow network lies within the papillary layer of the dermis. The epidermis is supplied by diffusion from this shallow network and both networks are supplied by collaterals, and by perforating arteries that bring blood from deeper layers either between muscles (septocutaneous perforators) or through muscles (musculocutaneous perforators). This redundant and robust blood supply is important in flap surgery because part of the supply will be cut off. The remaining blood supply must then keep the tissue alive until a more optimal supply can be restored through angiogenesis.

Bum is a chiefdom in Bonthe District of Sierra Leone. As of 2004 it had a population of 18,827.
The Nyangatom also known as Donyiro and pejoratively as Bumé are Nilotic agro-pastoralists inhabiting the border of southwestern Ethiopia and southeastern South Sudan and in the Ilemi Triangle with populations residing in both countries.
The Nyangatom are members of the Ateker or Karamojong cluster that also contains the Turkana, Toposa, Karamojong, and Jie who speak closely related languages. They number approximately 30,000 with populations in both South Sudan and Ethiopia. Many Nyangatom are nomadic, residing in mobile livestock villages that may migrate several times a year. A substantial number of Nyangatom also reside in semi-permanent villages. It is common for individuals to move between mobile cattle camps and semi-permanent villages.
The Nyangatom have intermittent conflict with many of their neighbors, especially the Turkana, Dassanetch, and Suri. The Kenyan government provides some military support to the Turkana in these conflicts. Despite the risk of intergroup conflict, many Nyangatom have bond friends with members of other groups and there are trade relationships between the Nyangatom and many of their neighbors.
