Most commonly used to refer to Police Officers/detectives or anyone associated with law enforcement. Origins date back to an early 1970’s television series titled “Hawaii Five O”. Detectives on this
show were assigned to a special unit (Five O) and were savvy, aggressive and always apprehended the suspect. Much like the character “Daisy
Duke” from the Dukes of Hazard television series whose short shorts spawned a once
popular clothing trend with women very effeminate
men, the term 5 0 too has transcended television to urban slang.
