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?!'
