Jerks—you either know one, love one, or are one. This is a jerk-shaming session, appendages out, high key, full offense. I'm not talking those big jerkish actions, I'm talking the little offenses committed by people who were "raised in a barn" as your mom would say. There is a certain baseline level of politeness that you have to exhibit in order to qualify for participation in society, okay? I didn't just make these rules up.
