bã trầu
Definition
- Noun:
- Chewing residue: The fibrous, spent remains of betel leaf, areca nut, and slaked lime after they have been chewed together, typically spat out.
- (Zoology, archaic/obsolete): A term used in older zoological classifications to refer to certain small birds (e.g., sunbirds) or insects (e.g., water stick insects), likely due to a perceived resemblance in color or shape to the betel quid residue.
