Mentira is Spanish for lie or falsehood, and repeating it twice became a shorthand reaction online in Spanish-speaking communities. The short San clip circulates on soundboards and in chat groups because its meaning is clear from tone alone, even without context from its original recording. It is shared as a quick audio reply instead of typing, used in meme edits, gaming lobbies and family chats, and has stayed popular because calling out an exaggerated story is a situation that repeats in everyday conversation.
