What 膥 means
In Cantonese, 膥 means “egg” or “roe.” Alone, it can name an egg or ovum; 魚膥 means fish roe. The word is dialectal, so 蛋 is clearer in writing for readers beyond Cantonese.
A Cantonese vocabulary published by Robert Morrison in 1828 uses it in 剝壳鷄膥, a phrase for a peeled hard-boiled egg. Ernest John Eitel’s 1877 Cantonese dictionary records the same pronunciation for birds’ eggs and fish roe.
When is 膥 rude?
The compound decides whether it is rude. 雞膥 is a food term for a chicken egg; 膥袋 means scrotum and 膥子 means testicles, making those compounds vulgar. A lone 膥 is not automatically an insult.
Why does 膥 sometimes look wrong?
A reference drawing can be wrong while the character stays the same. A Unicode 16.0 review found a reference drawing for 膥 that showed 末 where the intended form uses 未. That is a glyph-source issue, not a different character.
A Taiwan national character record says default fonts from Windows 10 onward include 膥. The active font determines its visible strokes, so this uncommon character may look different across devices.
