A specific quality, or ethos, that distinguishes one's mustache as being of higher quality than one's peers. Possessing the quality of good mustachemanship involves not only impeccable grooming and regular maintenance, but also a confidence and swagger that says, "My mustache isn't just my facial hair, it's my lifestyle!"
Tom Selleck sure is sexy with that incredible mustache. He has great mustachemanship!
