During the chistmas season, pets and small children eat the shiny long strips of tinsel people used to decorate with, and pass them partially, leaving a series of strung festive turds connected to the anus,which must be pulled out by Mom when concerning kids, and by Dad when it's the doggy. This happened more often than not in the '70s; more of a rare occurrence nowadays, as tinsel isn't so popular.
Oh, look hunn, someone's got tinsel fanny! If it came out already, I guess she'll be fine.
Same as a donkey punch, except you use a shovel.
Dude! That mouthy bitch is headed for the green river.
