zoncera
Nonsense, bullshit, or a foolish statement. It refers to an idea that seems like an obvious truth but is actually a silly myth or a fallacy. (In Argentina, the writer Arturo Jauretche famously cataloged these as self-defeating myths or prejudices internalized by the middle class).
Stop saying zonceras. Your thinking has been co-opted by the ruling classes.
