Boss 

The narcissist asswipe you must put up with to put food on your table so your wife doesn't leave you. Demands the world from their employees, yet they put in minimal to no actual work in their own positions. Can be found grazing on fast food in their office like beasts in the wild when they're not yelling at some poor 20 something kid for being a mere minute late.

Greg Heffley: "Maybe if I kiss up enough, my boss who hates me will make me a boss!"
