The phrase it's ya boy became a staple greeting in online video during the Vine and early YouTube vlog era, when creators used it as a repeatable personal catchphrase at the start of almost every upload. Short intro clips like this one were then ripped, shortened and shared on soundboards and in meme edits, separate from any single creator. It survives because the line works out of context, instantly marking a fake confident entrance in gaming, reaction and chat videos.
