Boulder Fisting

The sexual act of moulding a 20-meterboulder into your hand and chiselling it into a fist with your dick/strap-on. Then during sex, ask your partner to turn around and bend over, only to surprise them with a rusty hard rock up their sweet ass and ravage their insides with vigor and tenacity, flamboyantly shaking your fist around their insides before suddenly pulling out to let the juices flow inside-out and offer it to Lord Ochinchin.

David: I gave my girlfriend a boulder fisting for her anniversary present.
Hans: What the fuck man, you literally just obliterated her?!

bouldering

The act of one man bashing his testicles against the testicles of another man, sometimes for comedic purposes, but most often for sexual gratification.

Dude... I was totally bouldering with Jared last night and it was WAY hot, but now my ballbag is all bruised.

Boulder

A very... unique town in Colorado. Population consists of Left-wingers, weird hippies, Buddhists, old people and hobos. It is an unwritten law in Boulder that you must never eat anything processed, only things from the earth. Another rule is that you must be as bizarre looking as possible. Oh yeah, the University of Colorado's there too.

I went to Boulder and found a hobo who had locked himself in a dumpster.
