Popping is a street dance adapted out of the earlier Boogaloo cultural movement in Oakland, California. As Boogaloo spread, it would be referred to as Robottin in Richmond, California, Strutting movements in San Francisco and San Jose, and the Strikin dances of the Oak Park community of Sacramento which were popular through the mid-1960s to the 1970s. Popping would be eventually adapted from earlier Boogaloo movements in Fresno, California in the late 1970s by way of California high-school gatherings of track & meet events - the West Coast Relays. The dance is rooted through the rhythms of live funk music, and is based on the technique of Boogaloo's posing approach, quickly contracting and relaxing muscles to cause a jerk or can be a sudden stop in the dancer's body, referred to as a pose,
