What Does OD Mean in Slang?
In slang, “OD” usually has “two meanings”. One is serious. The other is casual.

Examples:
- “He OD’d last night and had to go to the ER.”
- “That story hit hard. I heard she was almost OD.”
This usage carries weight. People don’t use it lightly.
OD Meaning: Overdoing It
Here’s where things shift.
In casual slang, especially in “New York City”, “OD” means:

This version strips away the medical seriousness and leans into exaggeration.
“Examples:”
