To be hystatic means to be so overjoyed, that you have now become a combination of the words hysterical and ecstatic. When the Jersey Shore producers asked Deena to define it, she replies: "Hystatic is, you know, when you're like super happy, and like, really happy."

(After Sammy returns to the Shore...)

"I like, was so hystatic that I almost cried."
-Deena (From Jersey Shore)
