Kevin Kline's facial expression when "doing his sister" in the 1988 film "A Fish Called Wanda".

That is all. There's nothing more to be defined.
In the movie. Twenty minutes in. Classic example of "vinegar strokes", although he's with his "sister"...

A method of swimming; you have front crawl, back crawl, breasts stroke, butterfly stroke and vinegar stroke. You prepell yourself through the water by girating your hips like your giving it to a woman.
You can prepell yourself backward using the same method...just by doing it on your back.
