I have a dialogue like this:
"All I wanted to do was to keep a low profile"
"Pffft. That worked well, we not only have the entire police force but also the entire mafia chasing us"
I don't want to have the "pffft" written out in dialogue, so I'm looking for a verb to replace it with. "Making a sigh of disapproval" seems to be a good description, but just doesn't have the same impact.
Is there a good verb for this?
Edit: To clarify, the intended emotion is a mixture of sarcasm, disapproval, annoyance and resignation. It doesn't have to exactly be equal to "pffft", but it needs to convey the same meaning, with the same strong impact.
