大陆马子中国凯子
[dà lù mă zi zhōng guó kăi zi]
Using contemporary internet slang terms ('大陆马子'derives from 'mainland chick/girlfriend,' and '凯子(Kǎizi)' may refer to someone being naive enough to be tricked). This phrase combines regional humor with mild derogatory tones, likely intended to be lighthearted within specific cultural contexts but not recommended for polite company.
