A moustache, plain and simple. The kind of word you use when you want to sound casually brutal about someone’s facial hair without writing a whole essay. Usually said with a bit of judgement, especially if it’s a dodgy, patchy effort or a full-on 70s throwback. Honestly, it’s impossible to say it without smirking.
