deflammatory

Unfavorable statements dat also raise one's blood-pressure.

If "INflammatory" statements ADD fuel to da flames of strife and turmoil, would "DEflammatory" speech tend to REMOVE da hot flickering conflagration from da tense situation --- i.e., "blow out da fire"...?? Maybe da idea of da term in dat sense would be dat da person who's being trash-talked about would still be fumin' mad, but whatever was being said caused him to feel "deflatedly extinguished" as far as his being able to "breathe fire" any more regarding said scandalous assertions/opinions about him.
