By the time they reach 14 years of age, males are remarkably horny, yet have no chance of getting a girl, and little knowledge of what to do if they ever did. They are bored with all forms of entertainment that they enjoyed prior to their current age yet are too young to do anything else, so they spend most of their time aimlessly roaming the suburbs on bicycles. Their boredem can eventually drive them to try stupid things (i.e. skateboard street luging) or to generally to destroy things. Their lives are mindnumbly devoid of any acheivement of worth. They are the main target audience of 70% of Hollywood films.
Nah, just a herd of fourteen year old boys rolling through on their bikes.
Damn, I forgot the 8th graders get out for summer before the other kids.
