да не, все правильно, это субкультура
Rudeboy, rudie, rudi or rudy is a
subculture that developed in the early 1960s in Jamaica. The term rudeboy came from Jamaican slang for "cool" or "hip," as the rudeboys, in the dancehalls and daily life, always dressed in the latest fashions. The term rudeboy may also have something to do with an extremely potent rum-based drink called "Rude to your parents," which was served at sound system parties. It may also be related to "rudeness," a term used in 1950s and 1960s Jamaica to refer to sexual intercourse.
