Milwaukie girl
Originating in Milwaukie, Oregon in the early 1980's, this sexual position involves a drunk girl in the doggy or semi - doggy position, looking behind her with a smile at the equally drunk guy trying to line up for entry.
"Dude, she did the Milwaukie girl last night." This line is usually followed by two Milwaukie boys high fiveing or more recently fist bumping.
