Get the osmug. 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".
