Originally, "muh" was a contraction of "muwahahaha," a sort of quick way of adding diabolical laughter to a phrase. It
now has a number of meanings, and is often used as a random interjection, or just dispersed throughout a sentence. At the end of a sentence, it adds an emphatic note to the whole. Standing
alone as an adjective, it means
something so bizarre or intrisically unique that it can'
t be described any other way. In front of an adjective or adverb, it acts as an intensifier. Muh is also associated with a pink paranoid
chihuahua, although experts haven't yet determined just how this applies. Muh can also be used as a greeting, a challenge, a threat, or just something fun to scream at the top of your lungs (an act referred to as a "screamuh").
