stunnerstache 

When a person intentionally grows a mustache that looks incredibly ridiculous to make them stand out.

Mustaches were big in the eighties and have always been big with cops and firemen. For some reason most normal guys can't pull it off. So they grow a stunnerstache as a prank to draw attention to their upper lip.

footnote: This also applies to both sexs.
