Schopfling, fem. n., Germanical madeupical for use in English, a shopping spree
Backstory: OCR software back in the 90s, having trouble with the odd German title such as Die Schöpfung (aka The Creation, a big choral work by Haydn). This comes out as "Die Schopfling", which lodges in my mind as the perfect name for a retail therapyoratorio should I ever get around to writing one. Well, I never did, but "Schopfling" has become my preferred term for any generally entertaining (as opposed to routine and chore-like) shopping expedition.
Usage: "It's Thursday night, let's go on a Schopfling." OR "I need a new wardrobe, I feel an Ikea Schopfling coming on."
