What Is a Botty?
"Botty" is an informal British term referring to a woman's buttocks or rear end. It is typically used in a lighthearted or humorous way and is not generally considered highly offensive.
The word can function as a noun for the body part itself or as an adjective describing something as having prominent buttocks. For example, someone might say, "She's got a great botty," or comment that a dress shows off her botty.
Because it is casual slang, it is mostly heard in informal conversations rather than formal or professional settings.
