Meaning of どうすんだよ


> example: "どうすんだよこの空気をよぉ！？"

Is it "What are you doing with this mood?!"? I can't make sense of it. The
line is from a manga.




'What to do about the air/atmosphere/mood?'. Without more context, it could be
something other than mood, but your translation is mostly correct.

Rather than 'What are you doing with this mood', 'What will you do (What are
you going to do) about this mood' would be a closer fit. As @ericfromabeno
comments below, there is an implicit placing of responsibility on the listener
and an urge for them to 'do something'.

This order of phrasing is very colloquial, and therefore not unusual in manga.

The use of よ and よぉ are superfluous to the actual meaning of the sentence, so
let's remove them and add a comma for the pause that would normally occur:

> どうすんだ、この空気を！？

Now, it is simply a case of using grammar to define the verb, direct object,
etc. and restructure the sentence into a more familiar order:

> この空気をどうすんだ！？

(どうすんだ is colloquial for どうするんですか, but I assume that you knew this).
