A swing-out. There are many ways of doing and here is what Frankie Manning - the man who saw how lindy hop was born and contributed a lot to its development - said about it in his book.
'Many of the other dancers developed specialties to distinguish themselves and wow the crowd. As Dawn Hampton, my good friend and one of my favourite dance partners today, likes to point out, “All of the Lindy hoppers at the Savoy had their own individual style. It’s not like everyone was going to class and learning someone else’s way of dancing.” A lot of the girls came up with their own way of swinging out. Some would back away from their partner; others would go out facing away from him, then flip around – whatever fir their fancy. No one ever told them they weren’t doing the Lindy just because their swing-out was different.

Joyce and Joe Daniels developed a swing-out that became known as "the submarine." He’d bend down so low that his left arm was coming up from the floor as he pushed her so forcibly that she’d shoot out. It was almost like what we call the whip today. We’d say, “Man you submarining that girl!"'
