微レ存

• Reading: びれそん
• Romaji: bi re son
• Kanji breakdown: 微 (slight/micro) + レ (abbreviation of レベル, level) + 存 (exist) → slight-level existence
• Pronunciation: /bi.ɾe.soɴ/

Meaning

An abbreviation meaning 'a slight possibility exists,' used to express that something is unlikely but technically possible.

微レ存 is a contraction of 微粒子レベルで存在する (biryuushi reberu de sonzai suru), literally 'exists at the particle level.' It conveys that a chance is extremely slim but not zero. Originating from 2channel boards, it spread to mainstream texting as a humorous way to acknowledge remote possibilities. Often used when someone is being cautiously hopeful or sarcastically admitting a tiny chance.

Examples

1. 合格する可能性は微レ存だけど、一応受けてみる。 There's a slim chance I'll pass, but I'll take the test anyway.
2. 推しが自分に気づいてくれる可能性、微レ存。 The possibility that my fave notices me — slim but not zero.
3. 明日晴れる微レ存に賭けてピクニック計画した。 I planned a picnic betting on the slim chance it'll be sunny tomorrow.
