The sound comes from Diacore's Scammer Moment video, where a scammer caught in an awkward exchange insists he pressed B. The oddly specific line was clipped and shared on soundboards and in meme edits because the panic in his voice fits far beyond the original call. Instead of sounding calm or convincing, he sounds like he is pleading with the button itself. That mismatch helped it circulate as a shorthand for desperate denial, bad excuses and blaming controls when something goes obviously wrong in a game or task.
