Doo

Doo is a juvenile way of describing human or animal excrement that is a shortened form of doo-doo. Parents commonly use it to avoid more direct or serious-sounding terms when talking to young children or in playful conversation.

For example, someone might say, "The dog left some doo in the yard," as a more gentle or humorous way of mentioning that the dog has pooped. The term is informal and lighthearted, best suited for situations where the tone is meant to be fun or non-offensive.

Because it sounds less harsh than the word "poop" or other related terms, doo helps make conversations about bodily functions between parents and kids a bit more comfortable or silly. Additionally, teenagers may use doo as an alternative to poop or cruder terms like "s***."
