Trying to find the best word to describe this response.

I say: "Hi, are you going to be in on Monday when we come round?"

They say: "Well, I do live here."

The intention being - who knows what they do with their life? It's a rhetorical, repsectful question. The response is barbed.

Okay, now that response isn't 'sarcasm'. Would you call it facetious? Sardonic? What is the word for that specific kind of cynical response / humour?

 

[banja]

Well done for missing the point so far. It's a subtle form of cynicism, but I'm unsure how it would be described as a form of language / humour.

I knew they would be in. I was being courteous; using the question as a confirmation for following details about when to turn up etc.

I wasn't being all butt-hurt by the response (we're friends, it's all good). I was just curious as to what this subtle style of language / humour was. I wanted to know this for my own interest, not because I wanted to pwn them / one-up them back.
