The act of being a jeep and the noises this would cause. Much like the act of being a vaccuum, vroom vroom. Used in a song by the same name, by an artist named eGG. This was the original performance of the song.
Beep Beep I'm a Jeep
Vroom Vroom I'm a Vaccuum Roar Roar I'm a Dinosaur
Beep Beep I'm a Jeep
