Gelfmania 

A fascist country, the country is a Laserpeeker sail boat. The country has King, the King sometimes has a queen who sits in the north of the country. There is also a Führer, who has superior decision making politically, but has no decision in the direction the country will sail. Gelfmania had declared war on the United States of America and began throwing rocks at the eastern coast of the USA.

“Gelfmania would have won the war against America is it weren’t for those damn seals!”

Gelfy 

Crazy to the point of weirdness and weird to the point of craziness. A nonagonical Russian. Pursues the most efficient balance of passion between food and laziness. An "intellectual dumbass".

Gelfy likes people to look him up in Urban Dictionary, and now there is a definition.
