The Himalayan Hunchback is an aggressive sexual act where the dominant partner punches the submissive in the back of the head, grabs their wrists and pulls them below the sub's buttocks while simultaneously penetrating their anal cavity and thrusting vigorously.
"I bet your old man never gave you a Himalayan Hunchback like that before."

"Never, your father is too gentle."
