Sorry guys I messed up on the terminology, forget the drop shoulder throw. I will try to explain the throw that I once used as best as I can.
Start with a tie-up, have one over hook in place (lets say your left). So your left arm has an over hook on his right arm. Drive your right shoulder into his right shoulder (step out with your left foot). Your body should move in a similar fashion as when throwing a swimming elbow. Your right arm under hooks his right arm just like a one arm shoulder throw. He should be bent over and off balanced. Now turn your back to him and scoot your hips under his and crunch down throwing him. Although my legs were quite bent my knees didnít touch the ground.
The guy I threw was a few inches taller than me; I donít think it would work too well against a shorter person but then shorter people usually donít pick fights.
