rainmaker 

The act of wandering in the desert, searching for the truth, whilst a choir of angels calls out one's name.

And I know of the pain that you feel the same as me. And I dream of the rain as it falls upon the leaves.
And the cracks in our lives like the cracks upon the ground. They are sealed and are now washed away...

Philadelphia Rainmaker 

To piss all over your girl right as she enters to join you in the shower, preferably when she is trying to act as sexy and seductive as possible.

Lisa seductively entered the shower and offered to scrub my back, but I instead greeted her with a Philadelphia Rainmaker. She was livid!
