The high school in Denver, Colorado, where two social outcasts, who were utterly and wholesomely sick of their bullying by the Cool Jocks and similar, went on a murderous rampage. Not that this was justified, but one can see why they did it - it wasn't Marilyn Manson, it wasn't The Matrix, it wasn't Neo-Nazism, and it wasn't Quake. IT WAS SOCIAL CONDITIONING. They had been led to believe by those at the school that their lives were worthless, so they thought, "Mise well take a few down on our way out!".
Of course, these two individuals are dead now, so we can't question them as to their real motives.
Neoconservative. Originally used to describe left-wingers who crossed the floor, neocons are on the authoritarian right, rather than the traditionally conservative libertarian right. They tend to be very pro-war and adopt the mentality of "We're better than you and we know it."
Some more vulgar people call them Neocunts.
"I don't really like Kerry, but I'd rather see him in power than those horrendous neocons who currently run things!"
Jock. US slang for the thick-but-amiable types that always do well socially. No idea how, for most of them are arrogant bastards who think that the world would blow itself up in mourning if they were to die. Also, they tend to lie for each othe to keep their noses clean.
Ostracism by such admirable specimens resulted in Eric Harris and Dylan Klebold perpetrating the Columbine massacre of 1999. So, in an odd kind of way, they're partially responsible. But that's neither here nor there. Feminine: preppy.
Scrub, an otherwise inferior person in some what way. Most often refers to social standings, i.e. anyone who isn't The Big Jock or similar. Also refers to people who failed to make it onto whatever team/club/board/group, and also, in online gaming circles, refers to somebody who is not inexperienced but not very good at it. Also used in Magic the Gathering, as a derogatory term for a player who is inferior to you.
