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.

Cum Gun V2 or commonly known as CGV2 on the internet. Occurs when your penis is as hard as a diamond and you feel as if your dick is about to explode like a 20 kiloton nuclear bomb. What happens is that your dick will start shooting load after load like a machine gun usually completely submerging the victim with your baby batter, with accuracy no one has ever seen before.
