It's called a lying rear delt flye. You lie on your side on a bench, holding a db almost overhead and a bit to the front with your palm facing UP - grasping the shaft between thumb and forefinger. So your upper arm is up by your ear. Then you raise the db in an arc up and to the back - hits your rear delt hard. Be careful not to straighten out your arm at the elbow at the top, since that hits the tricep. Keep the same shape in your arm and use your delt.
