A promise spoken as you cross pinky fingers that, if broken, gives the right to the grieved one to deglove, sever or otherwise critically injure your pinky finger.
My former friend and I had the pinky promise to go to our first Comic-Con together. She went without me. So, as a gesture of retribution, I tore the nail off her pinky finger. I am not cruel enough to disable her forever now, am I?
