I wasn’t sure, either.
ETA: The name is still trademarked!
Semi-relevant, but I can’t help thinking of it:
Years ago, the household I was living in took in a cat who’d been living in very bad circumstances, including being chronically half-starved. It took quite a while to convince that cat that yes, we could be counted on to give him more food at the next meal, so he didn’t need to eat, as fast as possible, anything and everything that he got a chance at. One night somebody left a full cup of cooking oil sitting out in the kitchen. That cat drank the whole thing.
It didn’t stay inside him very long –
(Humans, of course, are generally considerably larger than the cat was.)
Is that like a gallon for a person? Hmm, didn’t Lard Ass chug a bottle of oil in Stand by Me?
The cat probably weighed about 8 or 10 pounds at the time; but I don’t know if such things go exactly by size equivalents.
Castor oil. 
Oh yeah, castor oil. I’ve never even seen castor oil in real life. Did 1950s moms just keep it around for whenever they wanted to make their kids vomit?
Agreed. I had muffins and brownies both come out tasting very odd and figured out that it was using canola oil that I’d bought when vegetable oil was unavailable that’d caused the strange and deeply unpleasant aftertaste.
As for fat, I agree with whoever up thread said they cut almost all off before eating meat. Beef and pork fat are okayish in small amounts. Chicken fat is gross so that one I do cut off completely.
The intended use of castor oil is as a laxative, not an emetic.
Oh, and by the way, it’s probably still available at your local drug store.
The fat is the best part of a grilled steak, just like the skin is the best part of a chicken. That doesn’t mean I’d ever consider sitting down to a big plate of just fat or skin. But I would enjoy a bite of just fat or skin.
I discovered that if you have a leftover chicken, you can re-crisp the skin by peeling it off and sticking it under a broiler for a few minutes. Then you’ve got a nice plate of hot, crispy chicken skins to snack on.
I have actually seen bags of fried chicken skins at an international grocery store.
One guy told me his aunt did that. Butter was a treat and she would have a piece now and then, apparently, though I do not imagine she went around with a stick in her pocket. However, I actually met a guy who would go to the movies and, instead of munching on popcorn or sunflower seeds or peanuts or whatever, would pull a piece of cheese out of his pocket and start eating it!
