RCH

30 microns. Measured on a comparator by a physical scientist on his secretary's red cunt hair at the Defense Mapping Agency's Erskine Hall, Bethesda, MD sometime around 1980. No Shit. Your tax dollars at work.

"That RCH was yummy!" said Roy as he pulled it from his teeth.

RCHS

Raleigh Charter High School, a very prestigious charter school in downtown Raleigh. It is a hospitable environment to the growth and maturing of a variety of individuals. The blend of social and academic perfection led it to become top 9 on Newsweek magazine's school ratings in 2007. However, there has been a lot of recent trouble with drinking, drugs and other nonsense.

Hey, I go to RCHS.
Wow, I applied there. But I didn't get in. My life would have been so much better if I did.

Hey, I go to RCHS!
Oh, I know that school. It is really good at the academic competitions, like quiz bowl and world quest.
Yup, that is the one. We pwn.
