When a baby poops their
nappy/diaper. Fudge = poop, huggies = nappy/diaper. Used in
the Simpsons episode, 'Strong Arms of the
Ma.
Bart: '
Ew! Mom, I think Maggie fudged her huggies!'
Marge: 'Bart,
don't say it like that, you'll hurt her feelings. (sniffs) Geez,
Louise! How did you turn cinnamon applesauce into that?!'
