To insert, or to, more appropriately, THRUST the fist, shaped like a rock (boulder) into a sexual area of the human body. Once fully inside, the hand is to mimmick the movement of a large boulder and/or that of a crumbling rock, creating a sensation of both pleasure, and pain for the receiver. It is said that geologists (those who study rocks) can supply the best Boulder Colorado, as they can reenact the boulder with the greatest skill out there. Commonly practiced in the town of Boulder, Colorado, this trend is being spread throughout the world, known for its creativity and distinctive pleasure.

When you're finger-blasting someone's asshole and you find more chocolate than a See's Candy box, you just scoop it out and huck those Baby Ruths as far away from the action as possible.
So I stuck two fingers in my friend's cousin's asshole the other night and apparently the bitch had to shit. My dude, I was straight slangin' boulders. I'd show you the video but I left my phone in her car :(

When you encounter a person taking a boulder nap, you should check the area for loose rocks or else you might take one too!
