Gay Shotgun
When two gay dudes lube up their assholes and place them together to form an airtight seal and then one passes gas. It pushes the gas into the other gay dude and makes his stink star expand and pop a bit, thus giving pleasure.
Hey Thad, rub that maple syrup on my pucker and then back over here with your pants down. I had burritos for lunch and I want to give you a gay shotgun.
