The process of, after having a few drinks, hugging a plump girl who you are trying to hook up with and stealthily attempting to clap your hands. If you can clap your hands, you're good to go. If a girl fails the clap test, RUN.
Jesse: "I'm gonna gonna go for it!"
Joe: "Did you do the clap test?"
Jesse: "Nope, but I'm gonna go for it anyway."
