Definition

垫刀背

Literally means:

pad the back of the knife

Actually means:

be one' scapegoat; bear the blame of others

It figuratively means that someone is made to bear the blame of others or that he shifts his blame on others. It also means that one implicates others to bear the blame together with him. Derogatory.

比喻自己被动地替别人承担责任,或利用别人替自己承担责任。也比喻拉别人跟自己一道承担责任。具有贬义色彩。
