两边倒

两边倒

Literally means:

waver between two sides

Actually means:

sit on the fence

It means sitting on the fence without firm stand points and opinions, usually used to describe people who are chicken-hearted and sensitive to trouble without adherence to principles. They always lean to whichever side that gets the upper hand. Derogatory.

形容摇摆不定，没有坚定的立场和主张。多指胆小怕事，不坚持原则，哪边势力强就转向那边。具有贬义色彩。
