Berto Romero is a Spanish comedian best known for his long-running collaboration with Andreu Buenafuente, and this clip comes from that live programme, where his quick, deadpan exchanges became a signature part of the show. Short excerpts like dimelo mama circulated among fans as shareable audio jokes, especially in Spanish WhatsApp groups and meme pages, because the phrase is short, easy to recognise and instantly funny even without the original sketch. It survives as a reaction sound because it captures Romero's teasing comic persona in just a few seconds.
