The term "wifey" is typically used to refer to a woman who is married or in a long-term committed relationship. It can also be used as a term of endearment, similar to how some men may call their wives or girlfriends "baby," "honey," or "sweetheart." The word has become popularized through hip hop and urban culture, where it is often used in songs and lyrics. In this context, the term can be seen as a sign of respect and admiration for one's partner.
