I feel like it'd fit perfectly in Soul, the moment Joe falls down the open manhole he yells "fuuuuuuu..." and I wouldn't mind if they didn't even finish it.

Had to look up the scene and saw another where they say "Hell" a lot after Joe asks if he's in heaven or hell ( h-e-double-hockey-sticks). Granted, it is the souls of unborn people, but it's still kinda funny to think about.
