According to Robert Walton
Goose bumps, goose flesh, goose pimples, chill bumps or the medical term cutis anserina, are the swelling on the skin at the base of body hairs which may occur when a person is cold, scared or in awe of something. Basically it’s a rush of adrenalin. To be stimulated or overwhelmed is a very individual thing, depending of course what turns you on. It might be a structure, a view, a painting, a book, a person, a voice, or in my case, music.
