One thing I dislike the most is a slacker.

me too a slacker by definition is someone who avoids work and basically has no work ethic

That is so hard especially knowing they get paid the same as you and you are working, it is not know for sure but the term started either in 1790 or 1898

Exactly and I  think it is out rages like you are getting paid to do nothing at all there are some hard working people in the world and slackers make them look bad or try to.
