West Coast Swing is a partner dance derived from Lindy Hop. It is characterized by a distinctive elastic look and is danced primarily in a slotted area on the dance floor. Within the spectrum of partner dances, West Coast Swing is one of the most improvisational. The origin of the slotted style was an invention of Hollywood film makers who wanted "to avoid filming the backs" of dancers.
Whips are the backbone of WCS that lead into more advanced stylings. This eight-count basic resembles the whip of Hollywood-style Lindy Hop. The follower stays in her slot, while the leader steps in and out of the slot, creating a smooth, elastic look.
