Kenji filled up his hard drive with Spiderman and Spongebob. Now he's talking about moving to America. He's such an Ameriboo.

A history or alternate history fan who is firmly entrenched in the belief that the WW2 United States was the best military in history, without a single flaw. Effectively, an Ameriboo is any obsessive American Military fanboy/fangirl who doesn't like historical facts getting in the way of his militaristic fantasies. While not necessarily, many Ameriboos are firmly entrenched in the belief America was, and is the best Country in the world, and will forever be the best.
