狗与翔是对好友
[gŏu yŭ xiáng shì duì hăo yŏu]
This could translate literally to something like 'Dog and Feces - Two Close Friends', which might imply a humorous, crude way of defining an unlikely friendship or companionship between two different elements or entities where there is an unexpected harmony. However, it may also reflect a self-deprecating humor of a deep friendship between individuals.
