A sex move where the
woman is menstruating, is on top riding the man, and goes to reposition herself and has to grab the cock to reinsert, thus getting
blood all over her hand, reinserts and starts riding the cock again, proceeds to
slap the man's face and yells "Wilson!" -a la the volleyball in the movie "Castaway" and continues riding the "waves" as the man will usually will start bucking.
