This porn video tag, "ts-hookers," consists of two parts. "TS" stands for "transsexual," which refers to individuals who have undergone, or are in the process of undergoing, gender transition from male to female. In the context of porn videos, transsexual performers usually exhibit a mix of both male and female physical attributes.
The second part, "hookers," is a slang term for prostitutes or sex workers who offer their services for money. This suggests that the video may involve scenes where the transsexual performer(s) engage in sexual acts as part of their occupation as a sex worker. The overall meaning of this tag is thus that the porn video features transsexual sex workers providing sexual services to clients or other participants, often involving explicit and detailed depictions of their activities.
