Calling Police Five-O Comes From the Show Hawaii Five-O

If you are familiar with street jargon, you are aware that "Five-O" is a reference to the police. Then, why is the question. What possible connection does Five-O have to the police? The answer to that, or at least a made-up version of it, is in Hawaii. One of the first widely watched police procedural TV shows was the 1968 debut of Hawaii Five-O.

Police were commonly referred to as "Five-O" throughout the 1970s, and the name is still used in some places today. The fact that the show was redone and is still on TV is beneficial. However, Five-O didn't imply anything, unlike certain police jargon that appears on TV, such as police codes for crimes like the infamous "187," which was purportedly Los Angeles police code for murder. Therefore, the phrase originated from the program. It wasn't appropriated from pop culture or even the actual police. As a homage to Hawaii being the 50th state, it simply refers to the division where the cops worked at the 50th precinct on the show.
