Fatmouse 

1. A large rodent capable of eating a man.

2. A large rodent bent on world domination

1. Fatmouse+You=Fatmouse

2. (excerpt from Fatmouse website)Fatmouse is coming and he has a message and you are not going to like it. Fatmouse will consume your poor thin world and regurgitate it in his own image. Fatmouse Does not work fo ryou and he does not acknowledge your meager hopes and dreames. It is better to walk with Fatmouse than to be in his path, for Fatmouse must feed.

Fatmouse will consume you. He is in search of carbohydrates.
