Girls in their late-teens to 20's who utilize streaming services such as Twitch in order to flaunt their giant breasts to a large following, mainly consisting of horny men and 12 year old's who have never masturbated before. Usually they would play mainstream video and PC games in order to increase the boner-factor, as many of their followers have never been laid before. Some titty streamers may also place their leg on their chair in order to demonstrate how gorgeous they look.

While some titty-streamers are lovable and enjoyable, most of them are fakes who seek male attention.
