Bingo. The exact phrasing of the rule (9-5-1d) is: "Using disconcerting acts or words prior to the snap in an attempt to interfere with A's signals or movements."

This was asked by a fan, so the simple answer is no - it is not against the rules for the defense to deliberately make movements in an effort to the get the offense to move. There are extreme cases where it could be a foul, but in most cases this is not a foul.

And for us officials - There may be a penalty, but only if you decide that there is a foul.
