假朋友都是喂不饱的狗
[jiă péng yŏu dōu shì wèi bù băo de gŏu]
'假朋友都是喂不饱的狗' could be rendered as “Fake Friends Are Like Hungry Dogs That Can Never Be Satisfied”. Using animals as metaphors to represent types of individuals is relatively common in various cultures. In this scenario, it conveys a very cynical viewpoint towards fake friends who will always demand more from you without satisfaction, much like hungry dogs asking endlessly for food.
