what is od
That's a common misunderstanding. In a popular slang context, especially in an urban/hip hop setting, OD means to do something to EXTREMES. In other words, to go crazy with something. My friend OD'd on heroin but we kept him walking and made him drink coffee and he was fine, thank god.(clinical) Man, I know you gots a case of Cristal but don't OD! Dat shit is expensive dawg!. (In other words dont binge drink with expensive liquor)(urban/popular)
