Slang for police. Origin unclear, likely derived from the 1970's TV police drama "Hawaii 5-0" although it has been suggested to refer to the "5.0" emblems on Ford Mustang police cars used by many agencies in the late 1980's-1990's.

In 1982, Ford reintroduced a high-performance Mustang GT which opened the door for an entirely new era of the muscle car. Wringing a then-respectable 157 hp from its "5.0" (actually 4.94 L, 302 in³) Windsor V8.

The "5.0" Mustangs, cars that gave birth to an entire aftermarket performance industry, continue to remain extremely popular today.

Pronounced "five point oh."

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.
