Krumping, also spelled Krumpin, is a street dance popularized in the United States that is characterized by free, expressive, exaggerated, and highly energetic movement involving the arms, head, legs, chest, and feet. The youths who started krumping saw the dance as a way for them to escape gang life and "to release anger, aggression and frustration positively, in a non-violent way."

The root word "Krump" came from the lyrics of a song in the 90s. It is sometimes spelled K.R.U.M.P., which is a backronym for Kingdom Radically Uplifted Mighty Praise, presenting krumping as a faith-based artform. Krumping was created by two dancers: Ceasare "Tight Eyez" Willis and Jo'Artis "Big Mijo" Ratti in South Central, Los Angeles, California during the early 2000s.Clowning is the less aggressive predecessor to krumping and was created in 1992 by Thomas "Tommy the Clown" Johnson in Compton, CA. In the 1990s, Johnson and his dancers, the Hip Hop Clowns, would paint their faces and perform clowning for children at birthday parties or for the general public at other functions as a form of entertainment. In contrast, krumping focuses on highly energetic battles and dramatic movements which Tommy describes as intense, fast-paced, and sharp.CBS news has compared the intensity within krumping to what rockers experience in a mosh pit. "If movement were words, krumping would be a poetry slam." Krumping was not directly created by Tommy the Clown; however, krumping did grow out of clowning. Ceasare Willis and Jo'Artis Ratti were both originally clown dancers for Johnson but their dancing was considered too "rugged" and "raw" for clowning so they eventually broke away and developed their own style. This style is now known as krumping. Johnson eventually opened a clown dancing academy and started the Battle Zone competition at the Great Western Forum where krump crews and clown crews could come together and battle each other in front of an audience of their peers.
