Anybody want to define electricity ?

Good question. dictionary.com says "The physical phenomena arising from the behavior of electrons and protons that is caused by the attraction of particles with opposite charges and the repulsion of particles with the same charge."
Really, electricity is one of those words that is always used incorrectly. Most people are talking about the movement of electrons, which should be called current, not electricity.
As for the 25A killing you, and the example that was brought up in the same post, I don't know if it would have killed you. It might have, but chances are the current had a much easier path to follow than through your body, so you probably would've been fine, just a little hurt. Depends on the voltage.
I've heard that the voltage is what really scars you, amperage is what kills you. I got knocked off a ladder working on some lighting. Someone flipped the breaker while I was working, and as most lighting in highrises goes, the voltage was 347V. Fun fact, had the lighting been run at 120V there would have been more current running through the lines, but I would not have been hurt nearly as badly.
