I'm interested in hearing what it's like. Does it feel like the plane is about to fly apart?
The definition is as follows:
Severe Turbulence causes large, abrupt changes in altitude and/or attitude. It usually causes large variations in indicated airspeed. Aircraft may be momentarily out of control.
Occupants are forced violently against seat belts or shoulder straps. Unsecured objects are tossed about. Food service and walking are impossible.

Here's a direct link to the reporting criteria table in AIM/FAR.
