How it's used
Used primarily to describe involuntary defecation, often in children or as a hyperbolic expression for extreme fear. It carries a strong, slightly vulgar tone that is unsuitable for formal settings. When applied to adults, it is almost exclusively used as a taunt or a dramatic way to describe being terrified.
Examples
He used to soil his pants all the time when he was little.
Related words
Common mistake
Do not confuse this with 瀨嘢, which means to get into trouble or suffer negative consequences. While both share the same character, 瀨屎 is literal or used for extreme fear, whereas 瀨嘢 is a common slang term for encountering bad luck or a difficult situation.
