Meaning:

“哏,” originally used to describe something amusing, is a term from Chinese standup comedy that is akin to the English word “punchline.” The character “都” translates as “capital” or “city.” Tianjin, a city in North China, is acknowledged as the birthplace of Chinese standup comedy, and its residents are renowned for their humorous nature. As a result, internet users have coined the nickname “the city of punchlines” for Tianjin.

Example:

A: 国庆假期你去哪里玩了吗？

Did you go on a trip during the National Day holiday?

B: 我去了哏都，遇到了很多有趣的本地人。

Wǒ qù le géndū，yùdào le hěnduō yǒuqù de běndìrén。
