Pronunciation: [haθ ɡˈuːs bˈʌmps] (IPA) 
The correct spelling of the phrase "hath goose bumps" is actually "has goosebumps". The word "hath" is an outdated form of the verb "have" and is not used in modern English. Meanwhile, "goosebumps" is spelled with no space between the words and a single "s" in the middle. Its IPA transcription is /ɡuːs.bʌmps/, which helps to break down the pronunciation of each syllable in the word.
"Hath goose bumps" is a colloquial expression used to describe the involuntary appearance of small bumps on the skin, known as goosebumps or goose pimples. The phrase is derived from Old English, where "hath" is the archaic form of "has" and "goose bumps" refers to the raised bumps resembling the skin of a plucked goose.
Goosebumps, also known as cutis anserina, are a physiological response triggered by various stimuli, particularly strong emotions such as fear, excitement, or awe. When the body experiences these intense emotions, the tiny muscles at the base of each hair follicle contract, causing the hair to stand erect and creating the characteristic bumpy appearance on the skin. This occurrence is a remnant of our evolutionary past, where our ancestors would puff up their hair as a response to perceived threats, making themselves appear bigger and more intimidating.
The phrase "hath goose bumps" is often used figuratively to denote a strong emotional reaction to something, usually in the form of excitement or awe. It is commonly associated with feelings of anticipation, thrill, or being deeply moved by a particularly moving or inspiring experience. The expression can be used in various contexts, including literature, movies, music, and other forms of art to convey the powerful impact that something has on an individual, sending shivers down their spine and causing their skin to break out in goosebumps.
