NorwegianGrugledeYou're so excited for something coming up that you both look forward to it and not.

Literally it's the words "grue" (dread, not look forward to) and "glede" (happy, look forward to) combined, creating a word along the lines of "dread happily". It's a reflective verb: "Å gruglede seg". "Jeg grugleder meg til første skoledag" = "I dread happily for the first day of school."
