Popular phrase hollered by famous rapper Lil Wayne.
You obviously only hear music and don't listen to it. If you all would listen closely, he says "we are not the same I am a Martian".
In the movie E.T., the main character is a lost alien, who needs to "phone home" to be rescued. Weezy is simply referencing this Hollywood classic while simultaneously proving how we are not the same as him because he is an alien. WHATS UP
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."
