A cheerful CB radio voice says 10-4 good buddy, the Letterkenny trucking catchphrase used in memes and reaction videos to confirm a plan or joke.

This is a short, upbeat voice clip of someone answering on a CB radio with the classic trucking phrase 10-4 good buddy. The delivery is warm, friendly and a little playful, with the relaxed drawl you would expect from a driver checking in on the highway. It lasts just over a second, so it lands instantly without interrupting the scene around it. Used over a video, it turns a simple agreement into a joke, making the moment feel like a knowing nod between truckers. It works best as a quick punchline, giving viewers an instant, familiar laugh.

The phrase comes from CB radio slang, where 10-4 means a message has been received and understood and good buddy is a friendly term for another driver. It became part of trucking culture in the 1970s, when CB radios were a staple on long-haul routes and in road movies and songs about drivers. The clip is tagged with Letterkenny, the Canadian comedy series known for its rural characters and deadpan dialogue, which helped keep the trucking lingo in circulation online. Creators still use it because the phrase is instantly recognisable even to people who have never used a CB radio.

Pro Tip for Usage

Drop it right after someone agrees to a ridiculous plan, then cut straight to the action. Pair it with a truck horn or a highway shot, but do not repeat it, because the joke depends on its single snappy confirmation.
