Use of "bad"

Mr. Tom

A- I cannot stay here. The room is bad.
B- Hey, forget about the badness. We have no choice right now.
I'm not sure I would ever use "bad" as in these examples.

Mr. TomHow often do native speakers use "bad" as an adverb--and is it very informal?

We need the water bad.

Hi Tom

I'm quite sure I have used the word "badness" from time to time. Not often, though.

Your mini-dialogue is possible, I suppose. Nevertheless, it doesn't strike me as particularly natural/typical.

Using "bad" as an adverb is pretty common in informal English (here in the US, anyway).

How did you want to use "in bad"?

In some slang dialects, bad means "very good, admirable". The pronunciation is specific, though - the "a" is pronounced like "a" in "cat", but held for a long time.
I've never heard an idiom "in bad"
But you can have:
in bad weather
in bad times
in bad condition
in bad shape
in bad faith
etc. etc. etc.

Many thanks to all of you.

By "in bad" I meant "in trouble".



...but now I assume that it is NOT common in the US.

Where did you hear that usage and in what contex

In a short story written by an Indian author--I think R.K Narayan.

...he uses "in bad" in the sense of "in trouble"
