A person who is highly addicted to Oxycontin aka O.C.s.
O- Heads usually crush up the pills and snort them, even possibly injecting them. If you deprive an O- Head of their "daily dose", you are in for three kinds of hell!
Amanda is a real O- Head- She spends half her paycheck on those little pink pills!
