墙头草

墙头草

Literally means:

grass atop of the wall

Actually means:

fence sitter

Literally it refers to the grass on top of a wall swaying in the wind.

It figuratively means that one does not have his own opinion, but bends to whichever side that seems stronger. It connotes a sense of contempt. Derogatory.

长在墙上的草，风往哪个方向吹，它就往哪里倒。

比喻一个人没有主见，哪边势力大就倒向哪边。含有瞧不起的意味。具有贬义色彩。
