Something you can actually give to your OWN definition on Urban Dictionary!! I tried it.
My positive definition of George W. Bush isn't going so well. It has 300 thumbs down and only one thumb up, and that was mine.

what youtube has been reduced to, attention whores seeking attention by stating the title of the video and putting "thumbs up if" in front of it. Its pathetic, that they do this, but even more pathetic are the people that actually thumbs them up.

Begging for thumbs up is disgusting and pathetic, it shows that you dont have your own opinion and are only commenting to get attention
