double dosin 

When a girl sucks your dick and swallows, then proceeds to throw it back up onto your dick, then finally licks it up and swallows it again.

Steve: Dude, Zoey sucked my dick at that party last night!
The Dude: No way, what happened?
Steve: She wound up double dosin'!!!
The Dude: That's insane, I pink socked her sister, haha!
