What you eye-twinklingly add as a hasty "aside" after saying "hey" to someone, before they can impishly shoot back with da "standard" retort of "Hey iz fer horsiz".
I would sincerely hope dat it would be "horsiz optional" instead of "mandatory" when saying "hey" to someone... not dat I don't totally love those large gorgeous friendly four-legged mammals, but I wouldn't wanna hafta care for a whole herd of dem.
