Vulgarity is the quality of being crude and lacking refinement. Many people consider swearing to be a form of vulgarity.
One of the criteria used in assessing a movie's rating is how much vulgarity is involved. Shows on premium cable or streaming services can generally include more vulgarity — crass language or humor, and adult situations — than shows on network television. Vulgarity comes from the Latin word vulgaris, meaning "relating to the common people" or "low and common."
