humiliation
To cause a loss of pride, self-respect, or dignity. This tag is equally applicable to bullying or fetish content.
Some common humiliation actions can fall under public nudity, abuse, rape, body writing, being treated as a pet, or recording someone in a compromising situation.
A character should look embarrassed or upset by the action, or appear to visibly be degraded by it.
In most cases where a character is enthusiastically consenting with whatever is happening, the humiliation tag likely does not apply.
