"Derpstep" is derived from the Latin "derpar" (regular conjugation); which, being colloquial in nature, varies in meaning, but most commonly signifies the act of a mentally deficient individual eating his or her own excrement. The truncation of "derpar" combined with the suffix of "-step" creates a pejorative term reserved only for musicians with less talent than a boil on Ke$ha's cameltoe.
