Another word for nasty, but of a heightened nastiness. Old cheese is nasty. Old cheese with diarrhea on it is nersty. Often pronounced with a long "r" as in nerrrsty.
That movie was sick! But the part where his grandma vomited on the dog was nersty!

Did you hear about that man who killed his pregnant wife and ate the fetus? That is super nersty!
