fudged her huggies

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?!'
