Wikipedia Meaning and Definition on 'Horripilation'
Goose bumps, also called goose flesh, goose pimples, chill bumps, chicken skin, funky spots, Dasler bumps or the medical term cutis anserina, are the bumps on a person's skin at the base of body hairs which may involuntarily develop when a person is cold or experiences strong emotions such as fear, awe, admiration or sexual arousal. The reflex of producing goose bumps is known as horripilation, piloerection, or the pilomotor reflex. It occurs not only in humans but also in many other mammals; a prominent example are porcupines which raise their quills when threatened, or sea otters when they encounter sharks or other predators. Goose bumps do not appear on the face.
The "goose bumps" (also "gooseflesh", "goosepimples" or "chicken skin") effect gets its name from geese. Goose feathers grow from stores in the epidermis which resemble human follicles. When a goose's feathers are plucked, its skin has protrusions where the feathers were, and it is these bumps which the human phenomenon resemble. The term "goose bumps" is misleading because the bumps on a goose's skin does not qualify as piloerection, though birds do have the same reflex of extending their feathers out, a function of keeping themselves warm...[See more about Horripilation at Dictionary 3.0 Encyclopedia]
