The obvious aside, no; ‘duplicitous’. :-)
It describes its object in a suitably derogatory and precise way.
It also sets the tone for, enhances and amplifies the words around it; by dint of it being so specific and unemotional it also suggests that the full weight of its partner noun is that much more credible and warranted due to the carefully measured (and therefore seemingly more objective) delivery.
All in all, it turns what could be a throwaway insult into a deliciously pejorative phrase. Bravo.
