What is super-symmetry?

I recently watched the documentary Particle Fever and this word was used often. 

Can someone explain to me what it is and why Super-symmetry would be supported by the Higgs Boson having a mass of 115 Gev.

And since it has been found that that the Higgs Boson has a mass of 125 Gev what  could that mean?

Basically it's the idea that for each particle with a given spin (electrons have a half, photons have one, etc), there is another particle with a spin that differs by one half. Some processes might occur differently if, for example, these particles were being created, but there hasn't been any evidence of that thus far in the LHC experiments.
