What is the origin or the phrase "Happy horses h i t"
I know what it means today:
"Happy horses h i t" is a phrase that describes news releases, speeches and other official language often produced by public relations people that puts the best possible - if often unrealistic - spin on a particular subject. A great deal of happy horses h i t is often served up at political rallies, awards ceremonies, and in government and corporate communications in general.
But where did it come from?
