What does "被续了" mean? 我想这个穿着红色衣服的男孩已经被续了。


In this sentence, the word "续" means life-prolonging, and when people say this they usually mean that someone was being life-prolonged to somebody instead of someone was being life-prolonged by somebody. Why?
It's a Chinese (political) joke. It has been told that a boy is killed to lengthen the former (×2) chairman, Zemin Jiang. But it's not proven to be true yet. It's alright to used chatting with people of new generations in China. And it has somehow become a meme among them.

When people say 续命、续一秒、+1s , they are also talking about that.
