Request: Limiting the number of blatant Game of Thrones references in future?

The concept, sure. Using it as an exclamation though?

Even if you strike that one off the list, there is a veritable cornucopia of references to chose from.

We use "hell" as an exclamation all the time in English. If there are seven hells in their world, then they probably aren't going to use "hell" singularly. They'll say "hells" or "(number of) hells" most likely, the same way they refer to the Twelve.
