"wuss"? It is just too easy to ask the AI, and get back more information (which may well be wrong) than I wanted: "Wuss" and "woos" are both slang terms used to describe a person who is weak, cowardly, or ineffectual¹². The term "wuss" is more commonly used, while "woos" is colloquial and used primarily in Australia²³. Please note that these terms can be considered disrespectful and should be used with caution.
