Stating that something is not true.
Contexto cultural
The phrase '¡Mentira cochina!' is a playful, very informal way to call out a lie, often used among friends or with children. In Mexico, 'Es puro cuento' or 'Me estás cuenteando' are very common informal alternatives to 'Es mentira'. Argentines might use '¡Cualquiera!' to express that what someone is saying is a lie or complete nonsense. The term 'mentira piadosa' (pious lie) is the equivalent of a 'white lie'—a lie told to avoid hurting someone's feelings.
