goose bumps?

goose bumps? why not people bumps. lol. I have always wondered why they call it goose bumps instead of people bumps. If someone came up with calling it goose bumps then why not moose bumps, cheetah bumps, bird bumps, or cat bumps, even hippopotamus bumps. I've also wondered why we speech the way we speech now. We could be speeching like this: fring hinger linger caper sipped ziziziz zip wooooooosh camasas helwowo. You get my point? I hope you get it. Any way I've been wondering that for a long time now.
