Krumping is an urban street dance-form that began in South Central Los Angeles. It is characterized by free, expressive, and highly energetic moves involving the arms and chest, and has become a major part of hip hop dance culture alongside other forms, such as breaking, popping, locking, and freestyling. Krump is a relatively new dance-form. Like other styles of dance, Krump is seen by many as a faith-based art-form. Accordingly, many of its pioneers spell Krump as an acronym (K.R.U.M.P.), which stands for Kingdom Radically Uplifted Mighty Praise.
Krump's origination as a unique dance-form is widely attributed to dancers known as Tight Eyez, Big Mijo, and J-Smoove of Tha J-Squad in South Central Los Angeles.
Krump is an emotional and aggressive dance. It is similar in form and practice to traditional weapon dances, and for this reason is considered by many African-American krumpers to be symbolic or referential to their tribal roots. As such, dance "battling," a form of dance where competitors face-off in a direct and aggressive competition, is an integral component of krump. "Dissing" (mocking), and heightened moments of frantic, aggressive arm and chest movements (known as "buck" moves) are standard.
