gisdom
Ghost wisdom. The wisdom passed down from ghosts of past, present and future.  
Night Janitor:  What's that noise in the girl's locker room?
OH, GOD!  How did the Coke machine get moved in front of the stall?  Who turned on the fucking showers?!

Blonde girl Poltergeist:  It's meee.  Tee Heee.. and now you die.

Night Janitor:  Lord, save me from her wicked gisdom!  Those damn Wiccan kids must've done this.
