Arbiter 

Arbiter Thel 'Vadam (formerly "Thel 'Vadamee"), often simply referred to as The Arbiter amongst players, was a distinguished Sangheili. At the apogee of his career with the Covenant he served as the Supreme Commander of the Fleet of Particular Justice. However, following the destruction of Installation 04, he was stripped of his rank, and forced to don the ancient armor of Arbiter. He accepted the position of Arbiter to continue his service to the Covenant, even in his disgraced state. The Arbiter is always sent on a suicidal mission to claim great honor in death, so he was not expected to live. However, the Hierarchs (and later the Jiralhanae that the Prophets used to attempt to assassinate the Arbiter) underestimated his skill, and he survived. He, along with the rest of the Sangheili, allied themselves with Humans, after the Gravemind told him of the Halo's true purpose, and was betrayed by his Covenant brethren. He later swore vengeance on The Prophet of Truth.

Simply, Arbiter is god.

Arbitrator 

A judge, jury & executioner at a one stop shop.
Usually a posher version of a normal lawyer.
This rare breed of attornies mastered the art of ripping you off your life savings by enjoying government protection because their trials and secret and not published.

This is the type of lawyer that sits behind a mahgony desk sipping scotch and talking to his fellow Freemason friends about the beauty of the 1st amendment while you soil your a*# out in courts.

Trump decided to withdraw from NAFTA because he found that the arbitrators judgments were unfair towards the United States.

Arbitrary Facetime 

When a person spends time showing face at a place of work, family gathering, or at some other public or private commitment, for no other utility or purpose but for the sake of showing face.

I put in a 12 hour shift at the office with my door open, 8 hours of which was actually work, 4 hours of which was totally arbitrary facetime.

The Arbiter 

The Arbiter was a "Heretic" Elite blamed for the destruction of the first Halo discovred by the UNSC. An Arbiter is someone who is decides, and enforces and issue. The past Arbiter's of the Covenant have dealt with such situations such as those in campaign mode of Halo 2. (By the way, incase none of you pin-heads noticed, the Arbiter's voice is the same of 'Golaith' from Gargoyales.)

The Arbiter was ordered to deal with the true heretics of the Covenant
