krumping

Krumping is relatively new urban street dance-form that began in South Central Los Angeles and is characterized by free, expressive, and highly energetic moves involving the arms and chest. It has become a major part of hip hop dance culture

Krump is one of the dance style similar in form and practice to traditional weapon dances, and for this reason is considered by many African-American krumpers to be symbolic of, or referential to, their tribal roots. Dance "battling," a form of dance where competitors face-off in a direct and aggressive competition, is an integral component of krump in a similar way to the earlier breakdance battles, with "dissing" (mocking), and heightened moments of frantic, aggressive arm and chest movements (known as "buck" moves) being common.
