What 뽓 means
By itself, 뽓 has no fixed everyday meaning.
Hangul builds it from ㅃ (opening consonant), ㅗ (vowel) and ㅆ (ending consonant). The Korean word or dialect spelling supplies its reading.
An 18th century Korean vocabulary-manuscript tradition linked to scholar Yu Manju’s reading of Yeokeoyuhae lists it among syllables used for native words hard to write with Chinese characters. A 1989 orthography article listed it for 사이시옷, the ㅅ written in some compound words, showing that fixed Hangul sets could miss dialect and pronunciation forms.
In chat, it reads like a fragment of Korean spelling, not a clear reaction.

1Why does 뽓 show as a box on some devices?
Because that device's fonts have no glyph for it. The character is still correct and still copies correctly — the box is a missing glyph, not a broken character.
