A Potomac-area variant similar to a Cleveland Steamer or a Boston Pancake, but rather than dumping on the girl's tits, one should aim for the genitalia, and ideally get the feces caught in the girl's pubes. So-called because if one were a crab louse watching this unfold from said girl's pubes, this would resemble a huge brown comet streaking across the sky shooting out of the "moon" and crashing into the earth.
After the Redskins lost to the Cowboys, I realized the only thing that could cheer me up was sending a DC comet streaking across my girlfriend's vagina.
