pronoun
First-person pronoun used primarily by males. Casual to neutral; common among boys and young men, but can be used by adult men in informal settings. Less formal than 私 (わたし).
僕は学生です。
I am a student.
明日、僕の家に来ない？
Won't you come to my place tomorrow?
pronoun
Colloquial second-person use when addressing a young boy, often with a friendly or familiar tone. Not used toward adults or in formal situations.

noun
Archaic noun meaning a male servant or attendant. Not used in modern Japanese outside historical contexts.
江戸時代の武家屋敷では、僕が主人の身の回りの世話をした。
In samurai residences of the Edo period, manservants took care of their master's personal needs.
Originally a noun meaning 'manservant' in classical Chinese, adopted into Japanese with the same meaning. Its use as a first-person pronoun developed from humble self-reference, later becoming a casual male pronoun.
