Top quality, admired. Really hot shit. So good your shit even smells good.

A person who thinks they are “all that” believes they people should buy them lunch and open doors for them. They think they are so hot and sophisicated that they can attract anybody.
In the old days we'd have a saying for women who thought they were "all that" -------- Miss Fine Thang. The whole block would be in on it -- little kids would follow her down the street ridiculing her "Oh my, you walk SO FINE".

And people would be calling her that all her life.

Superior. Admired. A cut above. Possessed of the qualities envied by one's peers. Most often encountered when one guest on Jerry Springer feels another to have too high an opinion of themselves.

Meaning that one is on the top of their game. Also means that a person thinks they are the coolest, most badass person in the world. Most often it is only an opinion of the person. Often times the person who thinks they are "all that" is the only person who thinks they are.
"Look at that fool. That fucker thinks he is all that."

A comedy sketch show made by Nicklodeon. The earlier episodes being better than the newer ones. Popular skits were Repair man, ask ashley, superdude, and vital information for your everyday life.
Did you see the new episode of all that? it was funny.

Means -- as much good stuff as you can imagine.

I just noticed that Socrates said it first in Plato's Symposium (a dinner party story) when he was commenting on the kind of praise everyone was giving the god "Love" and how it might not be true praise, but maybe only flattery. It's liable to be exaggerated flattery because there is no one listening who really knows him (the god Love) who's gonna prove you wrong.
"And so you attribute to Love every imaginable form of praise which can be gathered anywhere; and you say that "he is all this," and "the cause of all that," making him appear the fairest and best of all to those who know him not, for you cannot impose upon those who know him."
