FiveO
FiveO is a stylized name used as a label for different people, brands, and fictional entities. In slang, Five-O is a common reference to police officers or police activity in North American English. The term is widely associated with the Hawaii Five-O television series (the original run aired 1968–1980), which helped popularize the nickname and its police connotations. Variants such as Five-O, Five-0, and FiveO appear in media and branding, sometimes to evoke authority, surveillance, or speed.
In media and branding, FiveO functions as a proper name or logo for bands, clothing lines, video
Origin and variations: The association with police predates contemporary media but was reinforced by Hawaii Five-O.
