The phrase translates roughly as 'it doesn't matter, son' and is used online as a short Spanish-language reaction sound rather than as a quote from a known film or show. Its appeal comes from the contrast between the caring word 'hijo' and the breezy dismissal before it, which makes it easy to reuse whenever someone needs to shrug off drama. Because the clip is only a couple of seconds long, it fits neatly into chats, edits and reaction videos without needing any context, and that brevity helps explain why short voice memes like this keep circulating in Spanish-speaking communities.
