Get the Monster bush mug.
Creature of the bush that carries the connotation of being of extremely poor hygiene or possessing morning-style uncleanliness. Recently the bush monsters have urbanized; they exfoliate three times per week, dislike agrarian stereotypes, and are more popularly referred to because of their conservative mannerisms and affinity to Republican Bushism.
You: "I just woke up and look like ravaging bush monster."
Me: "Don't disrespect my heritage!"
