While having sex in a porto-potty, one (near ejaculation) shoves his partners head into the blue watery substance that often settles in the bottom of a newly cleaned porto-john. As he is near climax he will pull his partners head back up and ejaculate onto his/her face. creating a look similar to that of the face paint in the movie brave heart. Crying "FRREEEEEDOOMMMMM" is optional.
personA: "Why the hell is Sarah's face blue?"
personB: "I took her out to the porto-crapper and gave her the braveheart"
