The porn video tag "ts-carmella-bella" is composed of the following elements:
1. "ts": This abbreviation likely stands for "transsexual" or "tranny", referring to a transgender individual, typically someone assigned male at birth who now identifies and presents as a woman.
2. "carmella": This is a name, possibly the name of the transsexual performer involved in this video.
3. "bella": This word translates from Italian to English as "beautiful". It's likely used here to describe the performer, emphasizing their attractiveness or appeal in the scene.
This tag, therefore, indicates a video featuring a transsexual performer named Carmella (or someone describing her as beautiful), who may be engaging in various sexual acts with other performers.
