要么 at end of sentence

[anonymoose]

Part of an online conversation went like this:

A: 火灾是你造成的吗？

B: 滚

B: 你造成的要么

I guess this should be translated something like:

A: Did you cause the fire?

B: Get lost

B: You caused it more like

However, I'm not really sure about the 要么 at the end of the final line. I guess this is very informal speech, not really conforming to regular grammar rules. But I would like to know, is my understanding correct? Could someone possibly expand on this use of 要么 and perhaps give some other examples?

Thanks.

(I know the 要么X要么Y construction)

The last line doesn't sound right, or at least complete, to me. I'm speculating that it might be a typo and is supposed to be 是么 instead of 要么, which would make much more sense to me.

I think this is a typo. In fact, it looks like a typo that a couple of my friends frequently make.

[L-F-J]

要么 can stand alone as "or", so it may be an unfinished sentence, saying "you caused it or.. (who did?)"

Really? And I just my friends drank too much coffee. I stand corrected.
