tener un rabo de paja
Meaning: To feel guilty or anxious about something, fearing exposure of a personal fault or secret.
Literally: To have a straw tail
Example: “Se puso nervioso al ver a la policía; tiene un rabo de paja.” — He got nervous when he saw the police; he has something to hide.
Origin: Descends from a fuller, older proverb: quien tiene rabo de paja, no se debe acercar al fuego — whoever has a tail made of straw shouldn't get close to the fire, since straw catches alight far more easily and dangerously than any other material a tail might be made of. A version of the saying is documented in Spain by around 1800, phrased as a warning that only someone without a hidden weakness could safely stay calm near danger. Rabo and cola have long been near-synonyms in Spanish for tail, with rabo the more colloquial, popular term and cola its more formal equivalent, and both versions of the saying survive today, describing someone whose own guilty conscience makes them anxious the moment a related topic comes dangerously close.
