New England Hot Stepper"
When you're fucking a chick while wearing big heavy wool socks. Just as you're about to cum, you rub your feet against the carpet hard and fast, sending a shock through the head of your shaft. If successful, yell, "'ere cums da hot steppa!"
It was chilly last night, so I pulled a "New England Hot Stepper" for jokes. She yelped like a dog.
