I learned that move in the streets as a child, and I can say that it works very well - especially when they land on asphalt or concrete.

Another good move, which I've never actually done myself, is to grab the guys shirt collars and smash the top of your head right into his face very hard. You might have a headache, but he's going to be in really bad shape after this. This is another good reason to fight with your shirt off, as another gentleman here suggested, lol!
