她我马子他我凯子

In colloquial terms in Chinese internet slang, '马子' means 'girlfriend,' and '凯子' could refer to someone who supports one emotionally and financially, usually in a positive light, like a lover or benefactor. So this name might mean 'She's my girl, he's my support.' This expresses the relationship status and dependencies that are close with others, but should notice that some words here may have negative connotations depending on the context.
