I will go first.
The most disgusting I would say is a mealworm. I ate it on a dare BUT surprisingly; it does not taste "disgusting." It tasted like I was chewing on wet cardboard. Don't ask me how I know what wet cardboard tastes like. lol I have no idea. lol But it was the impression that I got.
Some other weird things I've eaten is microwaved mayonnaise sandwich. lol But that was when I was desperate to eat and there was absolutely nothing to eat.
Also, I sometimes like to eat hard-boiled eggs and ketchup all mashed up together. But I rarely eat that "food" anymore lol.
