Have a sense of entitlement and require constant, excessive admiration
Sounds about right.
Expect to be recognized as superior even without achievements that warrant it
A check large enough to make Nike jealous.
Exaggerate achievements and talents
Check.
Be preoccupied with fantasies about success, power, brilliance, beauty or the perfect mate
Oh yeah.
Believe they are superior and can only associate with equally special people
"Community college is stupid."
Monopolize conversations and belittle or look down on people they perceive as inferior
I'm not sure you haven't ever had a topic that hasn't consisted of you ignoring or dismissing basically everyone else.
Expect special favors and unquestioning compliance with their expectations
"They should give me this giant loan despite having no cosigner or credit history and not having anywhere close to enough income to pay it back in a timely fashion."
Take advantage of others to get what they want
There's been ample evidence to suggest you would be doing this if you were smart enough.
Have an inability or unwillingness to recognize the needs and feelings of others
"My parents are so terrible for not cosigning on a $60,000 loan I have no demonstrated ability to repay!"
Be envious of others and believe others envy them
Sounds right.
Behave in an arrogant or haughty manner, coming across as conceited, boastful and pretentious
Eeyup.
Insist on having the best of everything for instance, the best car or office
Again, "community college is stupid and I have to go to this one university that some random forum said was the best."
Sure, diagnosing personality disorders is a whole lot more nuanced than finding behaviours that match the symptom list, particularly where those symptoms are often pretty vague, but you certainly tick off a significant number of those boxes. I've also seen "lashes out when their ideas are challenged or questioned" listed as a symptom in some other places, which is probably the most apt description of your topics ever.
