Pug, a slang word originating in the uk, is the congealed discharge from the
nose commonly known as snot. It is retrieved by inserting the finger into the nostril and gently scraping the contents out with the fingernail. This is a favourite pastime of children and
teenagers who often display it with great
pride. It can be eaten as it has quite a pleasant taste (so I’m told). This habit can cause others to express feelings of disgust.
