大姨夫请管好你的媳妇

'大姨夫 (dà yí fū)' is a Chinese familial term for your aunt’s husband. However, in slang usage it has developed the meaning 'man who likes showing off his relationship.' 'Please take care of your wife (媳妇 - xí fu)' implies telling him not to let his partner cause trouble, but sometimes it’s said sarcastically to someone when they are too proud about their partner’s behaviors, almost as if inviting them to handle the possible consequences caused by their own loved ones’ behavior themselves.
