Why Use Asshat?
Quite frankly, there is no better insult in the world than the word asshat. Think about it.
You are once again late for work, and the boss decides to chew you out about it. So he finishes his ten minute speech about how you should be prompt every day. Under your breath, you mumble the word 'asshat'. He will look at you puzzled (if the old man even heard you) and ask you what you just said. "Asset," you will reply. "That's a great asset to possess." You just made fun of the guy, and didn't get fired! Asshat to the rescue!
All the best,
