"Dororo" is a Japanese term often used as a porn video tag. It is derived from the title of a famous manga and anime series called "Dororo," which itself is based on an older Japanese folktale. The story revolves around a young ronin (masterless samurai) who travels across feudal Japan in search of the 48 demons that his father, an evil lord, had sealed within him during birth to gain power and immortality.
As a porn video tag, "Dororo" likely refers to content involving Asian, specifically Japanese, themes or settings (as the term is of Japanese origin). It could also represent scenes featuring samurai, ninja, or other martial arts characters, as well as scenarios that involve supernatural elements such as demons, mythical creatures, or magic. Additionally, it may be used to describe scenes with a historical setting or geographical location in Asia.
