The Japanese word “Baka” ばか (sometimes written in katakana: バカ) basically means “fool” or “idiot”. Depending on the nuance, context, and tone of
the speaker it can range from a playful “you dummy” – to an
offensive insult. The term is often
used in anime by tsundere characters; in this context, it is said in front of the boy for whom they have feelings, blushing and in a vain attempt to deny those feelings. Just like it happened at falsagds. She used to call jvazquesgds with names like: pizzone, bufalo, scrofa and idiota. Why? Because she was too afraid of what she was feeling. Because she feared he wouldn't feel the same.
Because it was easier to insult him than to kiss him. And above all because he was perfetto represented by those terms. In short, he is the CEO of "seccato" and of
those who "nuntefannocapimaincaz*o".
