The phrase comes from everyday Spanish slang where agarrando señal means picking up a signal and carnal is a familiar way to address a close friend. Online, the clip spread as a reaction sound for moments of poor reception, unstable mobile data and streams that suddenly turn pixelated. Its humour depends on treating a weak connection like a physical thing someone can chase or grab. It remains popular in short edits and chats because the line is instantly understandable to Spanish speakers and works without any visual context.
