I read your description, CH, and if I didn´t know how to do them it would have confused me a bit. Tough to describe in words. Here´s my effort.
Scott Press. Start holding the dumbells in front of your chest like two enormous glasses of German lager at the Haufbrau Haus in Munich. Both press the weight up(like a regular shoulder press) and rotate the wrists so at the very top of the movement you make like you´re pouring the room temperature full bodied brew directly on to your head.
Do like CH said, elbows back.
