In shorthand 2-D fighting
game notation, this stands for "cross up" or "cancel". A cross up is a move wherein the fighter launches an aerial attack that flies just over his opponent's head and clips him on the
neck. Sometimes called a "
neck hit". Quite effective but a little tricky to do. A cancel is a move that a fighter launches before a previous move is over.
