DP phone home

While you're fucking a girl, take her cell phone and slip it into her other end. Just before her climax, call it. The vibration will blow her mind. A great way to impress the ladies. LG Rumors work well. Blackberries work for the ambitious at heart.

girl- "I never expected him to call me back so soon! Boy it really blew my mind! DP phone home, you're my hero."
guy- "Next time its my turn."
