When a girl is giving you head, and when you're about to cum you punch her in the back of the head so your dick slides into her esophagus whilst you ejaculate.
"Man she was all like, 'don't cum in my mouth' so I told her I would never do such a thing, and then when the magic moment came, KABLAW! I gave her the Hoskins Punch. She was coughing up my unborn seed for three days!"
