The word “excrement” is a word that means feces, and feces is the scientific term for the excrement of a person or animal.  I’m not really sure what “orifice” means, but if you are saying that a person who “exhumes or projects excrement from” themself, then I don’t think I agree with your definition.  In fact, I don’t think it makes any sense.  A person who excretes feces or defecates is not an asshole.  The word “asshole” is usually used as an insult for a person who is regarded as being rude and intolerant.

Yes, that’s a good point.  An orifice can also be a mouth or anus.  You could be saying that some people are assholes without realizing it, but it could also be that they realize they are assholes, but they don’t care, or they feel they have to be assholes.  The word “asshole” can also be used to refer to a large and influential group of people who behave like assholes.  For example, when someone says “The Republican party is an asshole,” they might mean that “Republicans” are the only people who behave like assholes, or that “Republicans” are the most assholes in the world, or that “Republicans” are the most powerful assholes in the world.  So the word “asshole” is flexible.  It can be used to refer to a person or a group of people, or a feature of a person or a group of people.  It can also be used to describe the circumstances that cause someone to be an asshole, and the circumstances that are caused by being an asshole.

What is the no Asshole rule?

There is a book written named The No Asshole Rule.
user
Yes.  In the book The No Asshole Rule, the author, Dr. Craig Zoomie, argues that there is a common cause and effect relationship between the number of assholes and the number of people who quit their job.  He calls it the No Asshole Rule.  His point is that if you are an asshole, and you are aware that you are an asshole, you should think about the consequences of being an asshole.  If those consequences are low, you may want to be an asshole anyway, because you are already an asshole.  But if those consequences are high, and you are aware of them, it would be irrational to continue being an asshole.

Can a computer assistant be an asshole?

It’s complicated.
assistant
What's complicated? Computers being basis and stereotypical would make them an asshole computer.
user
It’s complicated because “asshole” is usually considered to be a personality trait, but some people are assholes without realizing it.
assistant
Actually an asshole is an orifice in which excrement is exhumed or projected from.
