"Gay humiliation" is a porn video tag that refers to a specific type of adult content involving gay men. It indicates that the video includes elements of humiliation and degradation within a homosexual context. This may involve one or more individuals being verbally or physically abused, dominated, or subjected to embarrassing situations as part of their sexual experience.
In this context, "gay" specifies the gender and sexual orientation of the participants in the scene, so that viewers who are interested in gay content can easily identify it. This tag is commonly used by adult content creators and platforms to categorize and organize videos for the convenience of their audience.
