To fill your hands with jizz. Then clap your hands to have jizz splatter everywhere.
Man dis girl was jacking me off and her hands were full of jizz. Then she got all excited with the jizz and was clapping her hands. Doing the jizz clap. The after effect was jizz on my bed, carpet, eyes, mouth, her hair, and my walls.
