The act of using a toilet plunger to unclog an asshole that has been stopped up with feces and food particles.
After swallowing too many pieces of gum, Kristen decided it was best to visit the doctor to get a butt plunge.

In the act of wiping one's bottom, when the toilet paper tears and, inadvertently, a finger plunges into the butt hole. (Occurs especially when using cheap toilet paper or when wiping too hard). Can result in a stinky fingernail.
Guy in toilet: Oh, dude, gross!
Guy outside: What happened?
Guy in toilet: I was wiping and I accidentally did the one-fingered butt plunge.
