Greasers are a youth subculture that emerged in the 1950s and early 1960s from predominantly working class and lower-class teenagers and young adults in the United States and Canada. The subculture remained prominent into the mid-1960s and was particularly embraced by certain ethnic groups in urban areas, particularly Italian Americans, Hispanic Americans, and Latin Americans.

Hot rods are typically American cars that might be old, classic, or modern and that have been rebuilt or modified with large engines optimized for speed and acceleration. One definition is: "a car that's been stripped down, souped up and made to go much faster." However, there is no definition of the term that is universally accepted and the term is attached to a wide range of vehicles. Most often they are individually designed and constructed using components from many makes of old or new cars, and are most prevalent in the United States and Canada. Many are intended for exhibition rather than for racing or everyday driving.
