DOS is an Ancient name handed down to young men who possessed the mind of a scholar and the skills of a warrior.

It was the name of a god, handed down to a man who embodied all the attributes considered god like. Strength. Charisma. Magnificence.

As a man, DOS roamed the earth doing good deeds, pleasuring women, slaying demons and beasts, teaching those who wanted to learn and allowing the people to bask in his majesty.

In the present day, very few men are afforded the honour of bearing such a name. When such a man is found worthy, it is betrothed upon him with grand festivity as this man’s entire life has seen him proving himself day after day in the most glorious of ways.

DOS must be spelt in capitals, as each letter is as important as the one that preceeded it
He spoke to them in the way you would expect a DOS to.

His performance was so good i think he is a DOS.

He used his body in a DOS-like way.

An early OS (operating system), that was very simple. Programs were booted after the C:\ command line. DOS was later borrowed by Microsoft, which wouldn't exist anymore if it weren't for DOS. DOS was used for classic games, such as Doom, Wolfenstein, and Quake. DOS remains in existance and is used for gaming, without having to deal with Windows errors. A new version of DOS is hard to find, but with the most current and currently most popular version being FreeDOS, DOS users are still welcome to play their old games.
DOS pretty much died out after Windows "borrowed" it.

The abbreviation for Descendants Of Slaves, an ethnic group in the Continental Americas made up of the descendants of the survivors of the Slave Trade genocide.

The culture of this ethnic group is a unique combination of surviving African customs mixed together with the customs of their enslavers, which varies from region to region depending upon the ethnic makeup of the areas from which and to which the slave traders traveled to buy and sell human beings.
Ethnicity (like DOS, Irish, or Italian) is a real anthropological (the scientific study of people) term, unlike "race".

DOS (descendants of slaves) deserve reparations from the government because the government allowed their ancestors to be enslaved.

Toni's mom is Italian, and his dad is DOS, which means Tony has mixed-ethnicity.

The idea of "race" is based in Degeneration Theory, which conceitedly assumes that European ethnic groups like the Norse and the Romans are inherently superior to African ethnic groups like the DOS and the Arabs.
