"Alirio" is a term that likely refers to Alirio Díaz, a Venezuelan composer and guitarist who was born in 1912 and died in 1989. It could be used as a porn video tag in the context of roleplaying or fetish content related to cultural themes or Latinx heritage. The term itself is not explicitly sexual in meaning but when used as a porn video tag, it would indicate that the content involves elements inspired by or paying homage to Alirio Díaz's life, work, or cultural background
