Do Porn Videos
The term "do" in the context of a porn video tag is likely referring to the sexual act known as penetrative sex, where one person's penis enters another person's vagina or anus. In some cases, it might also be related to oral sex (mouth-to-genitalia contact), but since the word "do" is more commonly associated with penetrative sex, that is likely the intended meaning. As always, context can provide clarity if there are any doubts about the specific act being referred to.
