Someone who spends all of his or her life trying to reach the top, without any regard to anyone or anything that gets in the way.
Someone who wants recognition for something that is pretty meaningless in comparrison to the negative effects caused by the actions of an individual.
In a nutshell: A person who achieves very little by destroying a lot, and expects praise - (often gets it by the ignorant individuals among us).
'I heard Jimmy won the Gold medal in the 2012 olympics!, what a guy!',
'dude, he baught that on ebay, its made of tin'
'geez, what a hoopstar!'
