"僕" (boku) is a Japanese pronoun commonly used by males to refer to themselves. It conveys a sense of familiarity and casualness, often used among friends or in informal settings. The term is typically associated with younger males, but some adults may also use it to express a relaxed demeanor. In contrast to more formal pronouns like "私" (watashi), which can be used by anyone, "僕" reflects a more laid-back attitude. It is often used in everyday conversations, literature, and media, making it a significant part of the Japanese language and culture.
