"Baka" is a Japanese word that translates to "fool" or "idiot" in English. It is often used in casual conversations to express frustration or teasing towards someone who is acting foolishly. The term can be playful among friends or more serious, depending on the context and tone of voice. In popular culture, "Baka" is frequently used in anime and manga, where characters might call each other "baka" during humorous or dramatic moments. This usage has contributed to its recognition outside Japan, especially among fans of anime and manga.
