A strict public school in Leawood, Kansas, and makes you want to go to a private school. While sitting in the office of this school you can watch the security tapes, or watch the fat kids come out of the nurses office with an ice pack. Mission Valley is also the school with the ESL (english as a second language) program where all the immagrants come from all around Kansas City and try to kill the kids from KCK. It's not very pleasant, some of the Chinese kids try to knife the Mexicans, and the Mexicans hit on the Blacks, while the blacks are into the white trash...its pretty much a horrible school.
Mission Valley Middle School is a place that you never want to go.

Nov 27 Word of the Day
A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.
That fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.
