When 69'ing a girl, you ejaculate a large amount of seamen into the air. With the seamen still in the air, you gently pull open the girl's vagina and let the "rain" fall into her.
I gave my girlfriend a rain gage for her birthday and now she keeps trying to predict the forecast of when I'm gonna make it "rain" on her again.
