Piece of Shit
In my searches, I have found that there is a simple diagram that explains how enjoyable a person is to be around.
Self-evaluation:
Question #1 : Are you prepared or unprepared for the situation you are entering?
Question #2 : Are you demanding or flexible with the situation you are entering?
If your answers are unprepared and demanding, you are actively participating as a piece of shit.
On the other hand, if you answered any other way, you are probably not too shitty.
