poster

Someone who uses his calve muscles to push himself through the air, making contact with another human being to throw aggressively a round object in a diameter of about a foot and a half. This action is usually followed by a loud scream coming from the person who performed the action and from the crowd. To perform the action, the attendant must have a certain amount of impulse in his legs, witch is more frequently described as "bunnies".

poster's madness

When someone gets a following (usually small, but it can be any size) on a social media site and it turns them into an insane diva who thinks they are far more important than they are, both to the social media site and to the world.
