fallen-boulder 

When you turn your shock-proof, water-proof phone to vibrate and effectively hide it in a woman's vaginal crevice and proceed to call your phone from her cell phone. Named for the Boulder by G-Zone. If your phone is not waterproof you may immitate the boulder by securing your phone in a condom(magnum if you have a blackberry) and knotting it at the end. May also be used with the alarm clock function for greater comedic efforts.

It was our first night together and I gave her a fallen-boulder sneak attack for wearing a short skirt with no panties.

I gave my girlfriend her 6 am wake-up call with a fallen-boulder.
