Os

Latin for "mouth". Used to describe the small opening of a woman's cervix, either on the vaginal side of the cervix, or on the uterine side.

Pronounced: "Oz" or "Oss"

"The cervical canal has a constricted opening or os at each end. The internal os communicates with the cavity of the uterus; the external os, with the vagina."

oS

oS stands for Old School. 'Tis an abbreviation for oS.

The lowercase-then-uppercase type is a way of making it look cooler. "oS" originated from Nitto 1320 Challenge, where we painted oS on our cars while on the team OldSchoolRacing, and even use oS on our cars to show that we've been playing for a long time and say it in chats across the web to this day. A note, oS should not be said in real life, you just say "Old School".

Ice Cube is Old School.
Ice Cube is oS.

The oS's are what makes OldSchoolRacing the best.
