That is colloquial terminology that has started to show up in some circles, probably introduced by NFL guys to NCAA guys. Usually, such colloquialisms are intended to speak to the lay spectator, at their level of rules understanding, as well as provide a one or two word foul description. Unfortunately, at least in this case, not even the lay spectator knows this terminology (yet). I hope they don't get to know it. I hope RR issues a bulletin directing that this particular term NOT be used. As unusual as this foul is, just take the extra few seconds to say, "Delay of game - number 77 - defense. The defensive player made an abrupt movement with the intrent of causing a false start. 5 yard penalty - 3rd down." And we wouldn't be having this discussion.
