“Hunter’s lingo” is the name given to any "code words" or hunting references used between the boys. Below is a collective list of the phrases used in the series, and their meanings:
- Dean: Dude, five-o. Take off.
- Dean's note to Sam "HILTS - ITS A STREET ASHLAND - MCQUEEN."
When Dean passes on the information that the anagram "danashulps" they had been trying to solve refers to a street called Ashland, he addresses Sam as "Hilts" and signs off as "McQueen"; Hilts is the name of the character played by Steve McQueen in the movie The Great Escape. This would have indicated to Sam that he should escape and check out Ashland Street.
- Dean: Go to the first motel listed in the yellow pages. Look for Jim Rockford - it's how we find each other when we're separated.
Sam and Dean's practice of picking the first motel in the yellow pages and signing in as "Jim Rockford." Jim Rockford is a fictional private investigator from the 1970s TV series, The Rockford Files.
The code word, "funkytown," is used between the brothers when one is in trouble. "Funkytown" was a 1980 song by the disco band Lipps Inc. and was one of the last big disco hits.
- Dean: Yeah, I talked to Ellen. Just got here myself. It's a real funky town. You ditched me, Sammy.
- Sam: He gave me a codeword. Someone's got a gun on him.
- Ava: Codeword?
- Sam: Yeah. Funkytown... Well, he thought of it. It's kind of a...long story. I... come on.
- Sam: That would explain why I have something stuck to my shoe.

- Crowley: Poughkeepsie.
- Sam: How do you know that word?

- Dean: What are you talking about? We're not even near there.
- Crowley: Yeah, like I said, you need to leave Poughkeepsie right away.
