Explanation

Something that's stylish or cutting-edge can be called mod. Your mod haircut and outfit might make you feel like the most fashionable person in your neighborhood. Just don't leave your hood. Mod is informal slang for modern, and the two words can be used interchangeably. You can also use mod to talk about the specific 1960s subculture of young jazz and soul fans and motor scooter enthusiasts. Young men and women who dressed in stylish, sophisticated suits and mini skirts, who favored Italian scooters and danced at clubs to R & B music were called mods, originally in contrast to the grungier "rockers."
