A place where a tyrranical goverment sends a group (or groups) of people that the leader/leaders of the tyrrany doesn't/don't like. Often times, it is a closed-off area that is surrounded by barbed-wire fences and search towers. The main reason that the tyrannical government sends these people to the camps is because they want them killed off because they think that that particular group of people is inferior or a danger to society. Not many people survive these camps.

A yellow bus transports children and teenagers to a concentration camp, nicknamed "school", five days of the week.

We spend, on average, seven-ish hours a day in this prison, where we are driven mad by gossip, drama, shithead students, fucktard teachers, and fights. In the long run, we spend fourteen years in these hellholes, when combining the time spent in grade school, Kindergarten, and Preschool, but not including College. Oh, and who can forget about schoolwork and homework? That also drives us insane.

A game played by marching bands. It is like the game Simon Says expect it is played with commands such as "Right-Face" or "One set of eight forward" but as the game progresses more complicated commands will be added to elimiate more skilled players. A player is out if he does not follow a command properly. The winner is crowned when s/he is the only one left.
After the band has formed a block they are prepared to play Concentration Block.
Drum Major (to band) : "Right-Face-Move!"
Band executes the move
Drum Major (to student who did not properly move) : "(Insert Name), you're out you turned left."

a detention facility camp established by a totalitarian dictatorship to place dissidents, ethnic or religious or other citizens, and other so-called "undesirables". Usually the prisoners are beaten up constantly, starved, tortured, forced to do hard labor and live in unsanitary filthy conditions, and eventually murdered. During the Holocaust the Nazis exterminated around 6 million Jews and 5 million "others". This included democrats, republicans, liberals, socialists, communists, Gypsies, people with disabilities, critics of fascism, homosexuals, Russians, Poles, Slavs, pacifists and much more. The inmates all got their heads shaved and were forced to wear certain badges on their clothing to identify their "offense" (yellow star, pink triangle, blue P, and so on). Some prisoners were medically experimented on, some had their body parts used to make things like book covers, lampshades, wallets, couches and wallpaper; but many more were forced to take showers of Zyklon B.
1. other fascist regimes, like that of Spain under Francisco Franco, established concentration camps.

2. when General Pinochet overthrew the government of Chile a soccer stadium in Santiago was converted into a concentration camp.

3. I saw the satellite photos of the Muslim victims in the Omarska concentration camp in the former Yugoslavia. A very terrifying and horribly brutal sight.

4. after 9/11 many people wanted to arrest and pen up in concentration camps ALL people in America of Middle Eastern and Indian descent, as well as ALL Muslims here too. History keeps repeating itself. What has mankind learned? Not a doggone thing!
