(USER) videos are hate videos indicating a good user depicted as an animated character, doing some stuff to a bad user, which is also depicted as an animated character. They are made by most users, except for Blue Mario, which doesn't take care of them and doesn't make them at all from some period after he made the last one of them. The reason they make is because of increasing hate of bad users. Most people put in their channel art, or on an intro, a wordmark "(USER) videos" or anything else related to them. Good users are those who hate bad users (or things), while bad users are those who love bad users (or things). Tommy62702 uses them quite rarely but he uses them.
