Pig's feet ARE gross especially pickled.
Fatback is a cut of "meat" off the back of the pig. It's mostly fat and it's fried until crispy. Sort of like pork rinds, but harder to chew. It's also very salty. I love it, but I can only eat a very little bit of it due to the salt. There's a really tiny layer of meat and a much larger layer of fat. sort of similar to bacon but sliced thicker and less meat and it's not "cured" like bacon.
The Confederate Army basically lived on fatback for 4 years as it was salt cured and could be carried easily in a haversack. It's another of those "poor people's" meats.
My husband is happy because the neighborhood church is having a fundraising dinner and serving chitlins. I've told him to eat it there and not even bring that nasty stuff in the house.
There's a lot that I will eat, but I don't eat "organ" meat. Especially the organ that is the digestive tract. EWWW
And I have at least tried most things before I say they are gross. I have had both chitlins and pickled pigs feet and one bit was enough to make me look for a place to spit it back out and be able to say they are GROSS.
