It's a common term. After you eat anything exotic,like say rattlesnake and come to the conclusion that it tastes like chicken? It seems that people say everything tastes like chicken. Like recently I had two of my very close friends who went to Thailand for new year party. After they came back and we went for a coffee' there was the talk of advantage and stuff. And it popped up they had frog legs. So what did it taste like "Chicken"! So why is that? While browsing I found this site.. Which will give you most of the answers you'd need about the topic. According to a chart(tree) on the site, we (humans) will or maybe will taste like pork.
