The warning in the title is the whole joke, using reverse psychology that makes listeners want to play the clip precisely because they were told not to. Sounds with this kind of dare title spread on soundboards and in group chats as dares, pranks and reaction clips rather than as actual phone alerts. Its thirteen second length helps the gag, since a real ringtone is usually short and ignorable. It remains used because the setup is instantly understood, even without knowing the original context, and the payoff is the awkward attention it creates.
