Back in the nineties I used to work in a porn store.
We had an entire part of the store sectioned off for gay hardcore. And in there we had subsections. One was Army. One was prison rape. And one was "Goat". And I remembered thinking "WTF does GOAT stand for?"
Well, I think now I know. I never watched any of the movies but I do remember the actors on the boxes where preppie looking mofos standing in front of million dollar mansions and wearing Abercrombie and Finch.
