50-50 slide

In skateboarding, a 50 50 is technically a grind, not a slide. To 50 50, get within a foot of the curb or ledge that you're planning on grinding then ollie towards it, in the hope of landing with both trucks on the curb or ledge. If you lean back to absorb the shock against the trucks you should pull the trick out pretty easily.
