You have questions, and we have answers. Read on as we explore the word boo (buː/bu/bo͞o) to uncover its definition, origin, and more.

What Is the Definition of Boo?

According to the Collins Dictionary, someone might say “Boo!” loudly and suddenly when they want to surprise, startle, or frighten another individual who doesn’t know that they are there — hence why it’s often said by ghosts!

With this definition in mind, there’s no denying that the name Boo is quite fitting for the small spherically shaped ghost that’s only viable when your back is turned when playing Super Mario Party games.

That said, our word of the day is also a sound that people make to show when they don’t like or approve of something or someone. For example, you might say boo after someone makes an unfavorable announcement.

Additionally, our word of the day, boo, can be used as an interjection, noun, and even as a transitive and intransitive verb:

  • Interjection — a shout that is commonly used to express disgust, chiefly at events such as a political meeting, theatrical production, or sporting event
  • Intransitive Verb (word forms booing or booed) — this prolonged sound is used to express disapproval.
  • Noun (plural boos) — a shout used to express contempt, disapproval, or scorn.
  • Transitive Verb — to show disapproval by booing.

What Does Boo Mean as a Slang Word?

Boo can also be used as a slang term of endearment to reference your significant other. As in, “I went on a date with my boo” or “Me and my boo-thang are headed to the amusem*nt park today.”

Used as an affectionate term, boo is synonymous with another slang word, bae. The term bae is used primarily by the younger generation to reference the most important person in their life, putting them before anyone else.

What Is the Etymology of Boo?

Dating all the way back to 1630-1640 and first noted as an expressive formation, boo is a derivative of the French beau.
