K.R.U.M.P.

Krumping is a relatively new form of street dance characterized by free, expressive, and highly energetic moves. The form began in South Los Angeles.

The dancers form groups known as "families" or "fams," reminiscent of B-boy breakdancing crews. Each of the families is organized around a krump dancer known as the Big Homie, who serves as both a dance instructor and a spiritual mentor of sorts. The internal structure of a family is hierarchical, with rank based on the expertise or respect of each dancer.

The families also function in mentor/apprentice arrangements. The Big Homies take "Lil' Homies", or younger, less experienced and/or beginner practitioners of Krump under their wing, allowing them to learn from them, and represent them in battle. Both titles are terms of respect. The relationship may actually resemble a surrogate sibling arrangement.

The Lil’ Homies often take on the name of their Big Homie. For instance, Lil’ Homies dancing under Tight Eyez include jr. Eyez, Lil Eyez, Soulja Eyez, Young Eyez, etc. Although a general hierarchy exists in terms of how the names are given out (for instance, the title "twin" goes to the dancer on par with his or her Big Homie's abilities), the naming is at the discretion of the Big Homie. Some will move all their dancers up by rank at once, or others will simply replace one "junior" with another if the first one leaves the family or loses the name in a battle. The ranks are: jr., lil, young, boy, kid, baby, child, tiny, infant, twin, prince, Souljah, General. These ranks are usually ranked differently in each fam, but usually jr. is right after the Big Homie.

A competition structure has developed as dancers vie for status and respect. Contests within the world of Krumping are called "battles" (as they are in b-boying).
