Cantinflear is a Spanish verb made from the name of Cantinflas, the Mexican comic actor Mario Moreno. The dictionary of the Royal Spanish Academy defines it as “hablar o actuar de forma disparatada e incongruente,” to speak or act in a nonsensical and incongruous way.
According to Excélsior, the Academy recognized the word in 1992. The newspaper quotes the definition with a further phrase, y sin decir nada, “and without saying anything.”
