An arrogant fascist with an inflated opinion of himself. Usually holds power over a chatroom or internet forum and seems to think that makes him a deity. Feels a constant need to demonstrate his supposed superiority by attempting to belittle and humiliate others. Doesn't really care about anyone but himself, and once someone stops worshipping him he will treat them like he does everyone else.

Get the sinistrophobia mug.A mid-1980s arcade game where you pilot a ship through an asteroid field mining for bombs to use against a super-demonic space robot called Sinistar, which is being built by swarming drones and defended by fast-firing tanks. Once Sinistar's construction is completed, he starts threatening and taunting you ("Run, Coward!") and makes a beeline to your sorry hide. The stress level involved gets ridiculously high. It is/was quite possibly the toughest arcade game in human history.
