บูด

Explanation

The core meaning is for food to spoil and develop an unpleasant sour taste or smell. It is common in everyday combinations such as ข้าวบูด “spoiled rice,” นมบูด “sour, spoiled milk,” and แกงบูด “curry that has gone bad.” By extension, it can describe a face showing obvious displeasure. In this sense, it is most natural in expressions such as หน้าบูด “a sullen face” and ทำหน้าบูด “to make a sulky face.”

Usage

It is commonly used at home or in food-service settings when checking whether rice, milk, curry, or similar foods have spoiled. In casual conversation, ทำหน้าบูด can describe someone visibly sulking or looking displeased.

Caution

บูด is not a universal equivalent of “rot.” It mainly suggests spoilage that produces an unpleasant sour taste or smell. เน่า is more suitable for decaying meat, fish, or produce, while หืน describes oil or fatty food becoming rancid. บูด is also normally avoided for sourness produced by intentional, proper fermentation.
