Smurdling

I had an active remembered dream night. Early this morning, I was in a play rehearsal (I was prompting from my script). One of my lines had me sneer at someone's disfavored cooking method. The actual line, with sneer, was "Smurdling." That being the term for the cooking method.

1) Why did I come up with this precise nonsense term and spelling? 2) Why did it stick through waking? Brain, you're weird.
