最推し

• Reading: さいおし
• Romaji: sai oshi
• Kanji breakdown: 最 (most/ultimate) + 推 (push/support) + し (nominalizer) → ultimate favorite
• Pronunciation: /sa.i.o.ɕi/

Meaning

Your absolute number one favorite — your ultimate bias among all the characters, idols, or people you support.

最推し elevates 推し (favorite) to its highest level with the prefix 最 (most/ultimate). While someone might have multiple 推し across different fandoms, their 最推し is the one who stands above all others. It is a declaration of ultimate devotion and is taken very seriously in fan culture.

Examples

1. 全ジャンル通して最推しはずっとこのキャラ。 Across every fandom, my ultimate bias has always been this character.
2. 最推しのグッズは値段関係なく即買いする。 I buy my ultimate bias's merch instantly regardless of price.
3. 最推しが変わるって相当なことだよね。 Changing your ultimate bias is a pretty big deal, right?
