A military academy. Or, as more loosely used, any kind of strict educational institution where, you -- the conscriptee -- can expect to receive lots and lots of discipline. Enrollment in such a hellhole is something parents (especially fathers) use to threaten their unruly or nonconformist sons.
EXAMPLE:

' Bunny was sent away to military school, an institution devoted to homicide and absolutely humorless obedience, when he was only ten years old. Here is why: He told { his father } Dwayne that he wished he were a woman instead of a man, because what men did was so often cruel and ugly.

' Listen: Bunny Hoover went to Prairie Military Academy for eight years of uninterrupted sports, buggery and Fascism. Buggery consisted of sticking one's penis in somebody else's asshole or mouth, or having it done to one by somebody else. Fascism was a fairly popular political philosophy which made sacred whatever nation and race the philosopher happened to belong to. It called for an autocratic, centralized government, headed up by a dictator. The dictator had to be obeyed, no matter what he told somebody to do. '

Get the military school mug.
a prison for average student athletes that didn't have the grades to be directly admitted into West Point. It is a place to be treated like a 12 year old and too lose one's soul, zest for life, and will to succeed.

an extra year of high school where students improve their study skills and are cooped up with the same 246 people for an entire year. The curriculm entails "buddy fucking", how to break the rules without being caught, and how to deal with a group of individuals who are either normal (rare), ignorant, or socially inept. If you like being told when to go to bed, cut off from society, socially and sexually deprived; this is the place for you.
