A sexual maneuver where the male is receiving oral sex from a female with a cleft palate. Since there's a naso-oral communication, the male can shoot his sperm out of her nose from the inside-out, making it appear that she just shot out a double-barreled snot rocket.
After pulling off the double barreled cum gun, I asked her if she wanted a Kleenex.
