意味

Big bro — a term of respect and affection for an older male figure, whether a literal older brother or someone you look up to.

アニキ is the katakana rendering of 兄貴 (aniki, 'older brother'), used colloquially to address or refer to an older male whom one respects. It carries a warm, masculine connotation and is common in contexts ranging from sports teams to yakuza dramas. In otaku and internet culture, it is also used to affectionately refer to admired male figures. The katakana spelling emphasises the casual, slangy tone compared to the kanji form.
