The act of getting high by snorting cocaine placed on your knuckles.
Those knuckle-heads were on a white knuckle ride all night!

When your knuckle are made white from grasping onto the bowl as you take a fierce dump.
That Chinese buffet cut me up. As soon as I got my ass home I took the white-knuckle ride.
