Alright, so check it:
Goblinpunk is a mixture of industriousness and "primitive" technology. It is huge underground cities made out of wood scaffolding and stone. It's catapults and trebuchets that look like they're held together largely by good luck. It's bone jewelry and feathered accessories with intricate designs carved in them.

If you've seen the first Hobbit movie (the only good one), Goblin Town is a perfect example of Goblinpunk.
