我媳妇再差用得着你说么我老婆再坏用得着你管么
[wŏ xí fù zài chā yòng dé zhe nĭ shuō me wŏ lăo pó zài huài yòng dé zhe nĭ guăn me]
'My wife might not be good enough for you but do you have to comment? Even if my wife acts badly, do you have to concern yourself with that?' It shows defense towards external criticism concerning one's partner, insisting personal matters don’t need others' interference. This may indicate protectiveness or possessiveness about significant ones.
