Happy St. Patties Day!
A phrase originating in the 1960's Counterculture.

It describes a person who has "tuned in, turned on and dropped out." In other words, it describes a person who has submerged themselves so much in the Counterculture (fully embracing a wide range of drugs- particularly psychedelic drugs, communal lifestyles, anti-materialism, radical politics, anti-authority and particularly anti-Police attitudes, alternate codes of dress and personal hygiene and often anti-social behaviors), and is thus "so cool," that they are largely unfit for and unable to participate in conventional society.

The phrase was invariably complimentary.

More recent usages tend towards extreme forms of irony. Often applied with considerable sarcasm as a form of insult it generally means a person who is deemed to have an inflated self-image. If the person displays any actual Countercultural leanings, they tend to be of the most mild possible variety.
"Dude, the Hells Angels are totally righteous. They're so out there, man, they're, like, too cool for school."

"That kid didn't come to my party. What does he think he is, too cool for school?"

The ock in your typical local community college class who resists (in the classroom) expressing himself or liberally speaking to people unless called on. He is typically sleepy-eyed with perma-frown/stance and at any and every alloted break, this guy will jump on the cell phone and become a totally different person. see also total dick and indistinguishable.
Sally: That guy in our Chem class seems shy, I wonder if I should go talk to him?
Alex: I killed some vagrants last Tuesday.
