I had to coin a word today.
I was writing some dialogue. Two characters were talking about a situation that had gone horribly wrong. “It went south,” as one might say.
But then the situation, which really couldn’t or shouldn’t have gotten any worse, did.
Saying it went “further south” didn’t work. It was so much worse than that.
So, the character, being a scientific, though puckish, sort, said the situation “went hyper-south. Four-dimensional. Like a hypercube. Hyper-south.”
Sometimes, you don’t know quite what is going to come out when you start writing.
Use it in conversation!
