Od

Od is an abbreviation primarily associated with consuming a dangerous amount of a substance, particularly drugs, leading to severe health risks or even fatality. This serious connotation has roots in medical and rehab communities, where it highlights the dangers of substance misuse.

However, OD has also found its way into more lighthearted contexts in everyday slang. People often use it jokingly to describe going overboard with something non-lethal, like indulging in too much food or binge-watching a favorite series.
