O/km
O/km is how many times you blow your load from driving a sick car like it's your life and your pants are your best friend.
I had 9 O/km today. My car is better than my ex and my credit score.
I got 4 O/km. The car was so good, it gave me a high five.
My O/km was 6. The car was so fast, it made me cry.
