Grimelkin 

"Grimelkin" is a German term derived from the words "Grimmig" and "Schlüsselkind". "Grimmig" translates as "po-faced" and "Schlüsselkind" as "Latch-key kid." Together, the term "Grimelkin" loosely translates as "red-headed stepchild."

The group of orphans were considered nothing but Grimelkins due to their rowdy behavior.

Grimbling 

To rub ones own excrement over the back of a horse before riding bareback for several hours then licking the beast clean. Done whilst listening to a collection of indy/electro music (consisting almost entirely of unsigned and/or foreign bands), followed by a few hours of chronic moping/depression/masturbation in ones room.

As I opened the door an unpleasant stench rushed out on a gust of air. Inside the room sat only a dishevelled, underfed horse, its naked master and a stereo playing that hungarian album by Venetian Snares. I knew for sure that she had been the victim of a vicious grimbling.
