An art form. The act of farting in one location and then dragging it down range with complete innocence. Similar to crop dusting which is done in an office setting.
A battle wagon is any type of makeshift vehicle that is epic enough to be titled as such. The more epic a battle wagon is, the more likely it is to be spelled with all caps. In order for it to be a true battle wagon, the operator or rider of the makeshift vehicle must yell, "BATTLE WAGON!!!" at the top of his/her lungs while it is in motion. Although most battle wagons are ill-considered for actual battle, the mere battle cry of the battle wagon is enough to cause the foes of its rider to quake in terror.
