The term "calatito" appears to be a slang term or misspelling. It is difficult to provide a precise description as it might not be an English term, and without further context or information about its origin or usage in porn content, it's hard to explain its meaning accurately. However, in general, tags in adult videos refer to specific actions, positions, actors, or other descriptive terms that can give viewers an idea of what to expect from the content.
If you could provide more context or information about the term "calatito," I would be happy to help clarify its meaning or relationship to porn video tags.
