Wait...that's not what it stands for?
As a side, I've only had one experience with Spam. I was either 16/17/18 (most likely 17 turning 18), and me and some friends were at a naval base for a training thing one of us convinced the rest to sign up for. Not anything too intense, we all had a great time. Got woken up at 4AM to swim in cold waters, had to do fitness stuff, but also got to kayak race, learned how to sail a couple different types of boats, and play volleyball/basketball. Wish I remembered more about what it actually was. But I digress...
One of the things we had to do was- one morning, they had someone take us on a boat to a private island that I assume they owned. The guy took us around the island, showed us the different plants on the island, what to watch out for, and let us use his boat to fish. He was gone by the afternoon (I believe our 'training officer', if that's what he was called, stayed with us though). We then had to spend two days/nights on the island, and were given a provision of like 2 cans of spam for the 6 of us in case we were unable to find/get food for some reason. First night we cooked up the fish and opened the spam-each of us tried it. None of us touched the spam for the remainder of the time after that.
