The given porn video tag "dotata" seems to be a combination of two words - "dota" and "tata". It could potentially refer to:
1. DOTA: Defense of the Ancients (also known as DOTA 2) is a multiplayer online battle arena (MOBA) video game. In this context, it may suggest that the scene involves players or characters from DOTA 2 engaging in sexual activities.
2. Tata: This could be a misspelling of "tits" or "breasts." If this is the case, then "dotata" may refer to a scene involving breast play, such as touching, sucking, or fondling.
Given that the term "dotata" is not a standard porn video tag and might be a misspelling or an intentional mix of words, it can be difficult to provide a clear meaning without further context.
