White-knuckle ride 

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.

Ride the White Knuckles 

Commanding a party to go get fisted.
"His" or "her" may be substituted for "the."
Usage is same as "get bent."

Related: 'getting a white knuckle ride' would mean 'getting fisted.'

That bastard had the nerve to complain about our excellent service? He can go ride the white knuckles!
