Hyphy (pronounced 'high-fee') is a style of music and dance associated with San Francisco Bay Area hip-hop culture. The term is a combination of the words "hyper" and "fly". It is distinguished by gritty, pounding rhythms, and in this sense is closely related to crunk music. An individual is said to "get hyphy" when they dance in an overstated and ridiculous manner, or if they get overly loud with other people. Most in the Bay Area would consider this style as acting "Retarded" or "Stupid Doo-Doo Dumb". Similar in some ways to Los Angeles-style clowning.
