Someone who can't simply be honorable, by accepting defeat and/or trying again. On the contrary, said individual or group engages in childish pissing and moaning; bitching about how it's not fair and the other side cheated, etc.
Al Gore, Cynthia McKinney and John Kerry are all prime examples of winners. You won't find a single sore loser in that jolly little group!

One who is in the process of losing in a fair competition, but ends it before it can be completed and/or blames it on other sources.
Ex) “oh darn, i guess neither of us win because there was lag, I guess we can’t do it” “whatever, you are just a sore loser” “nu-uh, you don’t even know the definiton of a sore loser”

The New England Patriots are sore losers. They cry and are very unprofessional on congratulating other teams that defeat them.
