How it's used
Comparing someone to a lump of rice implies they are slow, unresponsive, or lacking common sense. It is a common way to tease friends or colleagues who are zoning out or failing to grasp a simple situation. The imagery suggests a person who just sits there like an inanimate object instead of engaging with their surroundings.
Examples
Why are you acting so stupid, like a total idiot?
Related words
Common mistake
Do not confuse this with 飯桶, which specifically implies someone who is useless and only good for eating. 舊飯 focuses more on the person being dull, slow, or blank, rather than just lazy or gluttonous.
