Pointy Haired Boss
The Pointy Haired Boss (or PHB) is an archetype character invented by Scott Adams in his Dilbert comic. He is famous enough to [[w:Pointy Haired Boss|warrant his own article in Wikipedia, detailing his characteristics as]:
He is an icon of stupidity and of management, which in Adams' work are always presented as the same thing. That is, there are no good managers, and the best one can do with these people is avoid them.
Such people use PowerPoint, and are sometimes called powerpointy or to possess the power of pointy. These phrases emphasize that only a PHB would use Microsoft products to try to persuade people that bad ideas are good. Indeed that is why presentation products exist, and why they have been banned from all serious companies.
It has become popular among trolls to attach ", PHB" to someone's name as if it were an academic credential like ", PhD", when describing their stupidity.
