Someone who believes in a totalitarian state rule by a supreme leader (dictator) who controls everything possible and treats people harshly -- to gain the leader's own success,* to foment an aggressive military nationalism, and to promote a Social Darwinist belief that hard life strengthens the state by weeding out the weak.

2. A lesser authority (corporation, mayor, cop, boss, parent) who legally issues harsh, burdensome, micro-managing, insensitive, or uncaring orders -- especially when they know, or should know, that their goals can be accomplished with more autonomy and much less hardship or distress.

Benito Mussolini (Il Duce - "The Leader") was the Fascist founder and Prime Minister from 1922 to 1943, who built a cult of personality around himself using false media propaganda that he was always right, killed those relatively few unbrainwashed who opposed him, and unified Italy for an incompetent war to retake much of the old Roman empire.

Relating to the ancient Roman word "fasces", which is a word for a bundle of sticks and an axehead paraded by the Roman government, fascism is a word commonly annotated with evil.
Coined by Benito Mussolini after transferring from Socialism, the term "Fascist" refers to an extreme right-wing supporter who believes in either a Totalitarian or Authoritarian governmental structure.
The term was loosely stretched to cover Naziism, and since the end of WWII has come to be a derogatory insult flung between politicians and blue-collar worker's alike.

Viz. George W. Bush.

A totalitarian movement started and popularized by Benito Mussolini which, much like communism, stresses the state as the cure for societies problems.
What differentiates it from Communism is the focus on nationalism more than the workers.
Nazi Germany was inspired by fascist Italy, though there are some differences. Its Nationalism extends into racial superiority as a distinct tenant.
There is a misconception of Communism and Fascism being on different ends of the political spectrum, this is a myth created by the Soviets to brand enemies of the party (the fascists were competition).
Fascist and Communist states both supress the individual for the collective people, and in turn socialize health care, business (sometimes corporatism), and education.
Fascism is not inherently left or right wing but it shares its roots with modern liberal ideology, as well as in eastern spirituality (that's where Hitler got the swastika from) and marxism; not to mention a general disdain for all things Judeo-Christian (Il Duce, Hitler, Lenin, Stalin, Pol Pot and Mao all had an equal hate for Christianity).
That isn't to say that there isn't right wing fascism...its just harder to find. The most famous fascists, Hitler and Mussolini, were definitely on the left side of the spectrum.
