I've been playing Keystone for quite some time now. Even have a .rtf of oddball quotes from RP's Past and a short list of his own slang (obstinately, to develop the colloquialisms of his fictional homeland) that I'm waiting for the most opportune moment to utilize/develop further. 

Always on the lookout for as new piece of crude but descriptive slang, if any comes to mind.
