stands for Stupid Sasquatch Syndrome. Typically, people with this disease are extremely tall and fall down often. Their intelligence is highly affected because they are so tall and the blood has a hard time traveling to the brain. Another side-affect is that SSD'ers like to tackle handicapped people. SSD'ers named their own disease and did not (and still don't) realize that Syndrome does not start with a D and that the acronym does not fit.
