Rad Ratz is a term used in the Vancouver area, , specifically the East Vancouver neighbourhoods, as slang to describe a group of sketchy looking guys who are usually fucking around or loitering. The term originally stems from a suburban Burnaby group of high schoolers, who used the term to identify as a gang, but then grew to generalize any group of rowdy guys.
