Name that Lifting Exercise

OK Guys and Gals, I need some help on this one. One of my favorite weight exercises is something a trainer showed me years ago. I put it into my upper body workout at least once a week. However I have no freakin' idea what it's called and cannot locate it anywhere on the internet. I'm hoping one of the smart folk here can help me put a name with this.

First of all it's a dumbbell exercise. It's similar to a standing reverse fly, however instead of the arms straight out in front, you hold the weights around your waist area (elbows bent at a 90 degree angle). Additionally, instead of standing straight up, you do it with with a little bit of a forward lean (not bent way forward like a standing row). Then using your back and shoulder muscles basically do a fly motion but still keeping your elbows bent. When the trainer taught me this I remember the specific form he stated was to imagine your shoulder blades coming together behind your spinal cord as you do the motion (to help isolate the rear deltoids and upper back muscles I guess).

So can anyone help me out on this one? I really like the exercise because it gets a lot of work on your deltoids, upper back (traps in particular) and even your biceps (through static contraction) when doing heavy weights . It sure would be nice to actually be able to describe in simple terms (like an exercise name) what it is that I'm doing.

You mean external rotations ?

they can be done 3 or 4 different ways but most common is bent elbows, elbows stay on waist and arms roate out...good for rotator cuff ?
