Stevenson’s law, based off of Noelle Stevenson, writer of She-ra. She has said to assume all of the characters are queer/lgbtq in some way shape or form instead of the opposite which is usually true, for other shows at least, it has become a meme quickly in queer cartoon communities.

When you hide in a closet while two people are having sex. Right as they're about to cum, you run up to the girl, skeet in her eyes, and wave your hand in front of your face. Combination of the John Cena and the sniper.
You can't see me because I just DeShawn Stevensoned you.

How the guy gets close to climax is entirely up to him but just before cumming he pulls out and cums into the palm of his hand. He then takes that hand full of jizz and slaps the chick in the face with it. For extra surprise, the jizz-in-the-hand setup can be done in secret before slapping someone. This is more commonly known as the Creamy Stevenson Surprise.

Marc: Oh well then I would. Those are awesome!
