When you are fucking a girl in the ass on an airplane in the bathroom at 30,000 feet without a condom on. You cum in her ass, pull out, then strap a condom on and proceed to fuck her in the ass. When finished, when you pull out. Your dick is now officially a sky-line chili slaw dog.
Sky-line Chili Slaw Dog.
Sky = airplane bathroom
Sky-line Chili = the shit from her ass.
Slaw = your cum that gets on your dog from her ass.
Dog = your dick in the condom.
