A hand to hand combat fighting maneuver in which you yell out "Criss cross applesauce!" While simultaneously faking a right punch(criss), then a left punch(cross) culminating in a swift kick to your opponents junk (applesauce) Timing is everything in this maneuver. If executed perfectly, it is unblockable.
a way in sitting in which the knees are bent and the legs over lap (hence the criss cross) and the applesauce is a nice rhyme used to remind young children how to sit.
