The porn video tag "teen-ts-compilation" is a combination of three terms:
1. Teen - This refers to young individuals involved in the scene, usually around 18 years old or younger.
2. Ts - This abbreviation stands for "Transsexual." Transsexual pornography features performers who were assigned male at birth but identify and express themselves as female. They may have undergone hormone replacement therapy and/or surgery to align their bodies with their gender identity.
3. Compilation - A compilation is a collection or selection of different scenes, clips, or segments that are edited together into a single video. In this case, it suggests that the video features various teen transsexual performers in a variety of explicit scenarios.
So, "teen-ts-compilation" refers to a video containing multiple scenes with young transsexual performers engaging in sexual activities. This tag is intended for adult audiences who are familiar with these terms and have an interest in this particular niche of pornography.
