To have a moongasm, one must be looking at a picture of Michael Moon while masturbating. The completion of the moongasm requires the masturbator to be consuming mass amounts of reese's and then must finish off into a bowl of doritos.
I had a double moongasm after lunch when I was alone in the break room. Nobody will touch those doritos now.
