nail turd
When a woman is shoving her fingers up her boyfriend's butt and twisting them like a madman. The longer she does it, the more stinky and glorious the nail turd becomes. You gotta pop it out and take a sniff to see if it's worth eating.
My cousin did this to her husband and ate the nail turd live on Zoom. It was legendary.
She shoved three fingers up his butt and twisted like she was trying to break him in half.
He screamed like a girl and she laughed and ate the turd like it was a snack.
