The recently made up word 'doucherstien' is an insult. It can be used as a serious insult, or a friendly insult. Whatever. The word comes from the root words 'Douche' and 'Stien'. Douche, meaning a squeeze-bottle used for the clensing of bodily orfices (usually the vagina or the anus). And stien, meaning a german beer mug. Doucherstien means a German beer mug filled with dirty douche water. Douche. Stien. Doucherstien. There you go.
"That asshole is acting like a total doucherstien. I wanna kick his ass."
"Way to go, doucherstien!"
