Essential Japanese Slang for 2025
1. ヤバい (Yabai) - The Ultimate Versatile Word
Originally meaning "dangerous," ヤバい now expresses almost any strong emotion:
Positive: このラーメン、ヤバい!(This ramen is amazing!)
Negative: テストの結果ヤバい... (My test results are terrible...)
Surprise: え、マジでヤバい!(Whoa, that's crazy!)
2. 推し (Oshi) - Your Favorite
From the verb 推す (to support/recommend), 推し means your favorite idol, character, or anything you're passionate about:
私の推しは〇〇です - My fave is...
推し活 (oshi-katsu) - Supporting your favorite (buying merch, attending events)
推しが尊い - My fave is precious
3. エモい (Emoi) - Emotional/Nostalgic
Borrowed from "emotional," エモい describes something that hits you in the feels:
この曲エモい - This song is so emotional
夕焼けがエモい - The sunset is giving me feels
エモすぎて泣いた - It was so emotional I cried
4. ガチ (Gachi) - Serious/For Real
Short for ガチンコ (gachinko), meaning serious or genuine:
ガチで? - For real?
ガチ勢 (gachi-zei) - Hardcore fans/players
ガチでヤバい - Seriously crazy
5. しか勝たん (Shika Katan) - Nothing But Wins
Literally "only wins," used to express that something/someone is the absolute best:
推ししか勝たん - My fave is the best, period
日本のコンビニしか勝たん - Japanese convenience stores are unmatched
