Greasers were a predominantly youth subculture that originated in the 1950s among young northeastern and southern United States street gangs. The style and subculture then became popular among other types of people, as an expression of rebellion.
The name "greaser" came from their greased-back hairstyle, which involved combing back hair with wax, gel, creams, tonics or pomade. The term "greaser" reappeared in later decades as part of a revival of 1950s popular culture.
Although the greaser subculture was largely a North American youth phenomenon, there were similar subcultures in the United Kingdom, Australia, Italy and Sweden.
