Sore Loser 

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!

emo loser 

Any and all individuals that think that their usually short lives so far are "so f'**n painful" they have to whine and cry about it on a regular basis in order to feel "special".

Woe is me, I'm such an "Emo Loser", I feel more deeply than anybody else in the whole wide world, including starving and prosecuted people with actual problems, and if you use your first amendment right to critisize me, I'll beat you to a pulp!

Urban Dictionary loser

A retard who posts definitions conveying/supporting their own not-so-politically-correct opinions. Yes, this definition is not very politically correct either. That would make me a hypocrite, which Urban Dictionary losers are as well.

An example would be the guy/girl who wrote the first definition for SkullCandy saying that they were very poor earphones and that those who bought them were idiots, or something like similar. Funny that, I just bought some today and have to say they are amazing. He/she was just an Urban Dictionary loser trying to push their own opinions on other people via this wonderful service.
