A window air conditioner that is spitting water on the outside is normal as well as dripping water outside is normal.
But if your window air conditioner is spitting water inside the house through the air vent then it's likely that your drain hole on the outside of the window ac is clogged with dirt, grass etc and not letting the water drip out and builds up in the pan causing the slinger on the window ac fan to sling the water inside.
