The word appeared in late 2017 and was named one of China's top 10 internet buzzwords of 2018 by the National Language Resources Monitoring and Research Center. It combines 抬杠 (to argue pointlessly) with the productive suffix 精 — part of a pattern that gave Chinese internet culture 戏精 (drama spirit), 猪精 (pig spirit), and 杠精 (argument spirit). The 精 suffix implies someone has elevated an annoying behavior to a supernatural level of mastery, as if they've cultivated it into a demonic art form.

The metaphor runs deeper than 'argumentative person.' 杠 originally means a rigid bar or lever — the image is of someone who takes any statement and mechanically pries it apart, levering open cracks that nobody else would bother with. They're not offering a counterpoint; they're performing opposition as a reflex. In 2019, the term spawned 'ETC' as a synonym — because highway toll gates raise a bar (抬杆) to let you through, and 抬杆 sounds like 抬杠.

Now standard vocabulary across every comment section in China. Zhihu answers attract gangjing who nitpick definitions, Bilibili danmaku gets gangjing who correct irrelevant details, and WeChat group chats have the one person who responds to every shared article with 'well actually.' The term is occasionally used self-deprecatingly — '我不是杠精但是...' (I'm not a gangjing, but...) has become its own meme, because starting a sentence that way guarantees what follows is pure gangjing behavior.
