喂狗的青春何来真爱
[wèi gŏu de qīng chūn hé lái zhēn ài]
This username carries somewhat sarcastic and sad emotion towards the past life or youth that seems to be wasted on insignificant matters instead of focusing on finding true love, as if one's prime years were spent on useless tasks such as 'feeding the dog'. It conveys the idea that during youth, true love was not experienced due to preoccupation with other matters.
