No los escucho is the Spanish version of SpongeBob's way of saying he is not listening, and the line has become a popular short reaction audio in Spanish-speaking meme and messaging culture. Because it is only about a second and a half long, it fits easily into WhatsApp chats, short videos and reaction edits. Fans recognise SpongeBob's voice instantly, even without seeing the character, and the phrase works in almost any argument or teasing exchange. It also sits beside other SpongeBob reaction sounds, including Plankton's exaggerated outburst, which creators use for a similar moment of comic frustration.
