When a woman swallows cum in space, and due to the anti-gravity, the cum slowly trickles from her mouth, emulating a dragon breathing fire.
Man last night me and Jodie were getting down in my spaceship, and after I pulled a mean Dirty harry, she went and pulled a mean Cum Breathing Space Dragon.
When your poop is so large that it breaks the surface tension of the water from below. (similar in concept to how a whale or a submarine “breaches” the water)
When someone performing oral sex spits the male's own ejaculation into their face.
"Man, just when I thought I got a nice BJ, this hood rat gave me the jizz breathing dragon. My eyes nearly got stuck shut."
"Call me a sick bastard, but I was hoping I'd get a jizz breathing dragon as a birthday present, but she swallowed instead. I wish my girlfriend could be more adventurous."
