CRUEF == Careless, Reckless, Using Excessive Force. Sometimes abbreviated as "CREF".
But @CapnBloodbeard does bring up (to me) a very valid point. Your English FA/RA may state that "adopting an aggressive attitude" is a reason to caution as per their directives, but it's bad to suggest that this is from the LotG or that it applies everywhere. Here in Canada, an "aggressive attitude" would apply when the push is reckless or excessive force. A careless push (or lesser force, ie incidental contact) would not be considered an "aggressive attitude".
