The Black Diamond 

When you manage to shit without pissing in a defiant act of sheer will power.

Person 1: "Damn it I was selected for a drug test and I have to shit."
Person 2: "That's okay just pinch off the Black Diamond first."

The act of talking a hit and a drag in the same breath, holding it in, then talking a shot, a 5 hour energy/Red Line, drinking a beer, then exhaling. at the same time you can say, if you have smoked weed, cigs, drank alc and done an upper, you can say that you have done "The Black Diamond" that night.

Student 1: Hey, whats there to do at SJSU?
Student 2: Nothing, so lets do drugs

Student 1: Sweet! lets do "The Black Diamond!"

a characteristic of early model cadillacs used primarily by the urban community that was popularized in a classic song, "Be Thankful for What You Got" by one-hit wonder William Devaughn and has been covered and sampled many times over, most notebly in rap songs beginning in the early 90s.

Though you may not drive a great big Cadillac
Gangsta whitewalls
TV antennas in the back
You may not have a car at all
But remember brothers and sisters
You can still stand tall

Just be thankful for what you've got
Though you may not drive a great big Cadillac
Diamond in the back, sunroof top
Diggin' the scene
With a gangsta lean
Gangsta whitewalls
TV antennas in the back
