A whole new level above nasty
That was so nersty dude.

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!
