The phrase comes from everyday Spanish, where 'mañas' refers to tricks, bad habits or sly tactics, so the line is used to declare a space free of them.

This one survives because it is instantly understood, culturally specific, and flexible enough for games, arguments and jokes where someone needs to be called out without a long explanation.
