我系我丈夫噶太太我系我太太噶丈夫
[wŏ xì wŏ zhàng fū gá tài tài wŏ xì wŏ tài tài gá zhàng fū]
In Cantonese vernacular, this translates as 'I am my husband's wife, and I am my wife's husband'. The phrase plays on identity confusion or role reversal humorously. Such a nickname may be used jokingly or to indicate gender-fluidity in relationships.
