A derogatrive term for a small furry moustache, usually found between the upper lip and the nostrils.
Derived from the reference to a rodent on the upper lip.
"Yo my man! Look at that guy with the mousetache! He clearly ain't hip to facial hair styles like we are."
"Stop trying to be cool Ben, you don't speak like that normally and you just made up that term. Just face it, you cannot start a meme."
"Such a buster..."
A group of thin, wispy hairs located on the upper lip that the wearer believes constitutes facial hair. Much like he believes her thin, wispy cries constitute consent.
A group of bristles or hairs about the mouth of a man who cannot seem to grow it in fully. Sometimes this is caused by the subject going through puberty, but it is generally thought that Darwin's theory of evolution may take part in this phenomenon.(if a person is undesirable, his body may not allow him to have normal bodily functions...like growing hair on his face.) This act of trying to grow facial hair but horribly failing is usually perpetrated by child molesters and heshers for some unknown reason.(or possibly the Darwinist theory above)
