Shouting in Skyrim—a special ability that Dragonborn have—isn't a thing that exists, obviously. But if we were to make it real, getting a sound strong enough to physically move someone, like the Fus Ro Dah shout does, would mean suffering devastating effects according to Vsauce3.

Jesus. Uh, yeah, let's not try to recreate a Fus Ro Dah in real life and just stick to Skyrim.
