What 붚 means
It meant “drum.”
A passage from 1459 in 월인석보, a Buddhist text, describes the drum of heaven beating by itself. This shows 붚 was in use by then, not when it began.
Hangul was devised to write Korean speech; its letters form syllable blocks. In 붚, ㅂ starts the block, ㅜ is the vowel, and ㅍ ends it.
붚 for “drum” in modern Korean is historical, not ordinary usage.

1Why does 붚 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.
