怎么说？

[Obi1]

A guy added the following comment to another guy's picture on Facebook: 你累吗？(Are you tired?)
He replied: 怎么说？
What does that mean? "How are you speaking?"

Why 你说你累吗

 

[NewAmerica]

It is colloquial which is the equivalent of "啥意思?“（"what do you mean?").

 

[SuperXW]

Here, 怎么说(how to say) = 怎么解释(how to explain) = 什么意思(what do you mean).
