The phrase rata de dos patas comes from a well-known Mexican song that uses the two-legged rat as a fierce insult for a deceitful man. Over time, Spanish-speaking creators lifted the dramatic insult out of the song and turned it into a short reaction sound for social media, where it now appears in memes about betrayal, cheating, and fake friends. Its theatrical tone makes it easy to reuse across languages, and the talent tag in its title reflects how often it circulates in performance and talent-show style edits online.
