Hitch hike was a dance craze of 1960s. It started with the 1963 Marvin Gaye's hit Hitch Hike and refueled with the gold disc of Vanity Fare, Hitchin' a Ride (1970).
The dance is extremely simple and is based on the hitchhiker's gesture: waving the stuck out thumb. The classical Motown pattern is three times right thumb to the right over the shoulder, clap hands, three times left thumb to the left over the shoulder, clap hands. All this is accompanied by the shimmy body ripples popular at these times.
Since these times the dance move firmly established itself in various line, club and jazz dances, especially disco, and may be seen, e.g., in John Travolta's dance films.
The style of the move depends on the dance and may be accompanied with steps back or sideways or hip movements.
