You are likely aware that the term for a youth goat is kid, much like a casual term for human children. The origin of the word comes from Norse, specifically referring to young goats, its first known use was approximately 900 years ago. Over the centuries, the word kid expanded to people, particularly young, mischievous people, and is likely the origin of the word “child.” The meaning of the word kid expanded to a verb sometime around the 1800s meaning “to gently tease.” I hope that sometimes you get a chance to kid around with your pals.
