a dingle fairy
The dingle fairy is like the tooth fairy, but instead of coins, they leave you crumpled dollar bills and take your turd. It’s a terrible trade.
My mom left a dingle berry under her pillow and got a crumpled dollar bill. She’s mad now.
My brother got a dingle fairy visit and now he’s got a stinky turd in his pants.
I told my sister about the dingle fairy, and now she’s leaving dingle berries everywhere.
