The phrase "boy-crazy" is often used to describe a girl or young woman who is very interested in or obsessed with boys. However, there are several other synonyms that can be used to describe this behavior. These synonyms include "infatuated," "smitten," "enamored," "lovestruck," "besotted," and "charmed." These words convey a sense of intense attraction or obsession with the opposite sex, and they can be used to describe both men and women. While some may view this behavior as unhealthy or obsessive, others may see it as a natural part of growing up and exploring one's romantic interests.
