twainiac

A former student of the mark twain school, which featured grades 7 through 12 and offered kids who were coded as emotionally disturbed (nutty) a place to run amok with other such unbalanced and often dangerous fools. The school is located in rockville Maryland next to a large forest area. Staff members often restrained students physically then went home and masturbated to the memory of it. Mark Twain would be the last place you might want you're child to end up unless you were grooming them for a circus side show act.

That child just beat up that other child with a trash can, i think they might send him to Mark twain, what a twainiac he will be indeed!

trainiated 

The feeling of loneliness, despite being on a crowded train.

Similar to alienated.

As I shoved my way onto the train, I found myself feeling trainiated... I've never felt this lonely in my life. How can I feel so alone when I'm around so many people?
