Better still to report it accurately...it is only subjective if you don't have the definitions (which is why I'm hoping someone can dig them out)
Another "Pruner" posted on this subject some time ago. Most other "Expert Posters" mocked and ridiculed him about it, however accurate his/her posting may have been.

An excerpt from his/her original post:
"...
However, I vaguely recall that it applied to "Transport Aircraft," and that the document classified turbulence somewhere around the following values: - Light Chop = 5 – 14 knot changes in IAS
- Moderate Chop = 15-25 knot changes in IAS
- Light Turbulence = 5 – 14 knot changes in IAS, AND, 300 – 1199 FPM V/S
- Moderate Turbulence = 15-24 knot changes in IAS, AND, 1200 – 2400 FPM V/S
- Severe Turbulence = +25 knot changes in IAS, AND, 2500 - 2999 FPM V/S
- Extreme Turbulence = + 3000 FPM V/S...
