From an anonymous book, chapter 1, paragraph 3:

I spread my arms wide and leaned into the oncoming mass, blowing a whistle that was more noisome than effective.

(The protag is a police officer assigned to riot control.)

Heh heh. Let’s try that again:

I spread my arms wide and leaned into the oncoming mass, blowing a whistle that was more malodorous than effective.
