It's when you're fucking a girl with a condom on, and you're so drunk that you don't know if you're going to piss, or cum. You pull out, roll the condom down to the tip of your dick, and fill it with whatever fluid comes out. Then you take the condom, and slap the bitch accross the face with it. Right as it whips accross her face, when it is far to late for her to evade the swinging specimen, you yell "DUCK!"

"Dude, I'm so wasted, but this girl want's to hook up with me"
"So, she's hot, fuck her"
"I'm too drunk man"
"Just do the rubber ducky, she looks like a VD slut anyhow"
