It's possible that it's:
* A misspelling: Perhaps you meant another word, like "besos," which means "kisses" in Spanish.
* A regional term: Some words are only used in specific regions of Spain or Latin America, so it's possible that "bessos" is a regionalism you're unfamiliar with.
* A name: "Bessos" could be a surname or nickname.
Please provide more context if you can! What were you reading or hearing when you encountered the word "bessos"? This will help me understand your question better and give you a more accurate answer.
