Concha tu madre is a long established Spanish slang insult heard across parts of South America, especially Peru and Chile, where it works as a strong swear aimed in anger or disbelief. Online, the stretched shout version detached the phrase from real arguments and turned it into a reusable reaction clip. Short edits, gaming videos and soundboards spread the exaggerated delivery because Spanish speakers recognised it instantly and others understood the tone from the shouting alone. It remains used as comic swearing rather than a serious insult in most meme contexts today.
