When you perform oral sex on a girl with the hope of getting her so turned on she won't be able to resist when you come up and penetrate her. Usually done is a quick manner so as to avoid any hesitation on her part.
I was hooking up with this girl last night who was so hot, I desperately wanted to be inside her. She told me early on she would not sleep with me so I had to pull out the patented munch and punch, worked like a charm.
When you fail at something in life (eg. failing an exam or not getting a job), go home and spend an hour just standing in the shower, propping yourself up against the wall with your eyes on your feet.
Caleb knew the only thing to do after he didnt get prefect was take a failure shower.
