A house party with no one there. A party that one reaches at the end of the night and everyone is too blown out to interact well with one another (like ghosts.) An empty house. Any location that is creepy.
"Let's get out of this party, this place is a ghost house!"
That thing where there are Boos everywhere and it’s kinda difficult to find the exit and it brings you on step closer to fucking Princess Peach.
“Oh shit, it’s a Ghost House!”
