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.
That asshole better shut his mouth or he's gonna get the ole criss cross applesauce!
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.
