双厨狂喜shuāng chú kuáng xǐ

厨 here is fan slang for a devoted fan. It comes from Japanese anime fan slang, through a pun between the Japanese words for “kitchen” and “middle-school kid”. 双厨 is a fan of two things at once, and 狂喜 is wild joy.

The trigger is a rare meeting: two characters, games or stars that never appear together, in the same frame. If the two often appear together, it is not 狂喜 any more.

It is still common under videos, game news and concert clips. Outside fan circles, people use it for any lucky double: two favorite foods in one meal, two favorite singers on one stage.

It grew up as a 弹幕, a comment that scrolls across a video on Bilibili. In December 2020, Bilibili put 双厨狂喜 in the top five of its comments of the year, next to 爷青回, the comment of the year. Users sent more than 2.2 billion comments that year.

Sina’s report on the list gave an example: a Bilibili fan edit that paired Lin Daiyu, the heroine of Dream of the Red Chamber, with Voldemort. A viewer who likes both could greet it with 双厨狂喜.
