This is a Spanish saying used to dismiss an additional task or problem as insignificant, especially when one is already facing many challenges or is in a formidable position. The imagery of a tiger implies that adding one more stripe makes no notable difference to its nature or power.

It’s often used with a dismissive, almost playful tone when someone is already handling multiple responsibilities, reflecting a deep-seated resilience in the face of overwhelming circumstances.

You’re so street-sharp that nothing slips past you. The joke compares that “knowing” to the taste of fried fish, because saber in Spanish can mean both to know and to taste.

People say it like “sharp as a tack” or “too smart for your own good,” with affection and joking awe.
