A thing you find in the middle of nowhere. It doesn't know any language so it grunts. It's completely barbaric, and unfriendly. It has four arms and is neither male or female. It's completely disgusting and vicious.
The other day I thought I spotted a sheebo and then realized it was my sister, and then realized sheebo is my sister. FML.
