I found a variety of mustache slang, but my favorite came from my Webster’s New World thesaurus: soupstrainer.
A mustache blog offered some other slang: grass grin, lip foliage, face fungus, and nose neighbor (another good one). Anyone else have any good ones? And what’s your favorite?
Mustache (or moustache if you’re a Brit) comes from the “Middle French moustache, from Old Italian mustaccio, from Middle Greek moustaki, diminutive of Greek mystak-, mystax, meaning upper lip, mustache,” according to Merriam-Webster online.
