鸡蛋糕!! - Kueh Bahulu  

定义：
一种带有玩笑意味的感叹语，用来形容别人傻乎乎、迷迷糊糊、太单纯，或做了令人哭笑不得的事情。

词语来源：
原本指传统糕点“鸡蛋糕／Kueh Bahulu”。在新马华人口语中，因为“鸡蛋糕”听起来滑稽又无攻击性，后来逐渐演变成一种轻微吐槽或代替粗口的感叹词。

例句：

• “你连钥匙都忘记带，真是鸡蛋糕！”

• “这么明显的骗局你也信，鸡蛋糕啦你。”
  

Definition:
A teasing or mildly scolding expression used when someone acts silly, blur, naïve, or overly innocent. Sometimes exclaimed jokingly: “Aiya, 鸡蛋糕!”

Origin:
Originally refers to the traditional sponge cake known as Kueh Bahulu, popular in Southeast Asia. In Singapore and Malaysia, the phrase evolved into lighthearted slang because “鸡蛋糕” sounds comical and harmless, making it useful as a substitute for stronger vulgarities.

Example Usage:

• “You forgot your own birthday appointment? 鸡蛋糕 lah you!”

• “Don’t be so 鸡蛋糕, obviously it’s a scam.”
