Dierks Bentley's new song, "5-1-5-0," has been a huge hit this summer on 101.5 KNUE and around the world. Not only is it catchy and fun, but Dierks uses lyrics that make the listener actually want to pay attention just to understand what the heck he's talking about. We did some digging and found out what "5-1-5-0" means, so next time you're jammin' in your car and someone asks, you'll be the winner of that day's random trivia.

By definition, 5-1-5-0 is police code for a person who is mentally ill or crazy.

Dierks and co-writer Jim Beavers were texting one afternoon and throwing ideas around when Dierks sent a simple but memorable message that read "Fifty-one-fifty … is anybody with me?" as a funny rhyme. The two talked about the love they had for the Van Halen album titled '5150' (pronounced fifty-one-fifty), and the phrase never left Beaver's head.

They changed the pronunciation of the numbers to five-one-five-oh, and began writing from there. One day while on a run, Beavers passed a cop car and thought of the slang term for police, which is 'po-po'. He put the two together and there came the hook of the song: "5-1-5-0, somebody call the po-po." The song became about a fellow who was going crazy just at the thought of his lover.

Here's what Beavers had to say about the song lyrics:

We were a little concerned that people wouldn’t know what ’5-1-5-0′ or ‘po-po’ meant, but ultimately decided that’s what made it cool and interesting. If they knew, they knew. If they didn’t they would find out. There’s been lots of songs like that that have been huge hits, especially in other genres.”

So, it's only customary to leave you with the video!
