情侣大陆马子装港逼本地凯子装洋佬
[qíng lǚ dà lù mă zi zhuāng găng bī bĕn dì kăi zi zhuāng yáng lăo]
This reflects cultural blending and mimicry where people in mainland couples (perhaps pretentious ones, '马子zhuang gang bi') imitate the style of those from Hong Kong while local guys (kazes - referring to gullible persons easily fooled) pretend to be Westernized individuals. It has a somewhat derogatory tone toward people trying too hard to fit into certain social stereotypes or lifestyles.
