When a person uses a bathroom stall glory hole, while positioning themselves just right so they can defecate into the toilet next to them while recieving favors through said glory hole.
John walked into the stall with the sole intention of a number two, but the inviting voice from the other side of the stall's glory hole was too much for him, and he found himself caught in the midst of a blumpkin surprise.
