When you get upset. When you feel too much. When you go too hard. You've OD'd. Yes, that's right, 'O.D.' = overdose, and in the Bronx vernacular, OD does not only refer to excessive consumption.
"Yo - miss - that's O.D." is what they say when I assign a lot of homework
"Woah. She O.D.'d," they muse when I get angry and yell at a student
If students teasing each other cross an unspoken line and make one another upset, their actions are summed up. They O.D.'d.
O.D. can be good too, if I make them brownies, they tell me that they are 'OD good'. If they have a crush on someone, they tease them about liking them O.D.. If they get a good grade they are O.D. happy, and for a vacation, they can be O.D. happy. It's the word that gives oomph to all of their moments.
Here's hoping that everyone O.D.s a little today - in a good way.
