Pejelagarto is a freshwater gar found in southeastern Mexico, and in Tabasco the word became a nickname for Andrés Manuel López Obrador, who is from the state and is widely called El Peje. The shortened, joking form otro pejelagarto spread in Spanish language chats, edits and political humor posts as a way to react to his mentions or appearances. Because the reference is instantly understood in Mexico, the short clip keeps circulating as a compact reaction sound even without any visual context from the original post or conversation where it was first shared online.
