The exact origin of the 'what chu mean, my boy' clip is unclear, which is typical of short reaction audio that circulates through meme pages, edits and soundboards rather than a single traceable upload. Its strength is versatility: the line works as a response to almost any questionable statement, so it shows up in gaming fails, storytime skits and comment-section-style edits. It sits comfortably alongside reaction staples like bruh and the drawn-out disbelief of oh my god bro oh hell nah man, earning its place through pure reusability.
