Grand Canyon

The act of taking a shit so wide that your asshole is left open, and appears to be a gorge like the Grand Canyon

I ate a ton of fiber this week, so when I shit today, I Grand Canyon'd myself.

Grand Canyoning

After titfucking a busty girl, cum between her tits unexpectedly and let the cum flow down between her tits.
Her tits represent the scenery, and the flow of cum represent river Colorado.

The phrase Grand Canyoning is a verb.

Example:
-"...I heard you had a 'special night' last night.What did you do..."
-"...I Grand Canyoned on her.She was surprised but it was amazing..."
