Goosefleshes, also known as goosebumps or goose bumps, are tiny bumps that form on the skin when a person experiences a sudden change in temperature or intense emotions. Some synonymous words for goosefleshes include piloerection, horripilation, cutis anserina, and fleshgoose. Piloerection refers to the involuntary contraction of tiny muscles at the base of each hair follicle, resulting in the hair standing on end. Horripilation is the medical term for goosefleshes, while cutis anserina is a Latin term that literally means "goose skin." Fleshgoose is another slang term that is used to describe the sensation of having goosefleshes. These synonyms can be used interchangeably to describe the same physical and emotional response.
