The term "transgal" is likely a combination of two terms: "trans" and "gal."
1. "Trans": This refers to a person who is transitioning from one gender identity to another, or someone who identifies as neither male nor female. In the context of porn video tags, it typically means transsexual, transgender, or non-binary content.
2. "Gal": It might be an informal or slang term for a girl, or could be related to "galactic" (related to space), which could suggest futuristic or sci-fi themes in the video.
So, the tag "transgal" likely refers to transgender, transsexual, or non-binary content involving individuals with futuristic or science fiction themes. This might include scenes that feature trans characters in a space or alien setting, or it could simply be a playful name for trans content. As porn video tags can vary and may not always adhere to strict definitions, this interpretation is subject to change based on the specific video's context.
