You bring a whole new level of stupid to the world, A smoke grenade doesn't explode, it puffs up and starts spewing smoke, if you watch the .gif you'll see a small explosion, because flashbangs explode which causes the bright flash that causes you to become disoriented. And smoke grenades wouldn't cause the man to fall backward in shock. So know what you're talking about before you go running your mouth you arrogant bitch.
