牛津词典2024年度词汇 Brain rot
Brain rot，直译为“脑腐”，这个词最早出现在1854年。美国作家亨利·戴维·梭罗在其著名散文集《瓦尔登湖》中，描述了他在湖畔一片再生林中度过两年两个月又两天的生活和思考。他在书中写道：英国尝试治疗土豆腐烂，难道就不努力治疗脑子腐烂？如今，年轻人经常在社交媒体上用“脑腐”来形容一个人的精神或智力状态衰退，尤其是由于过度消费琐碎的网络内容而导致精神和智力衰退。

Defined as "the supposed deterioration of a person's mental or intellectual state, especially viewed as the result of overconsumption of material — particularly online content — considered to be trivial or unchallenging", the term has resonated widely in a digital age increasingly shaped by social media. The phrase also refers to content perceived to cause such deterioration.

在过去一年中，“脑腐”一词的使用率激增约230%。牛津大学出版社的词典部门负责人卡斯珀·格拉斯沃尔表示，它的流行反映了社交媒体推动语言变化的速度惊人。

According to OUP, "brain rot" saw a significant surge in usage — 230 percent — between 2023 and 2024, as conversations grew around the negative effects of consuming excessive amounts of low-quality digital content.
