Crap On Two Legs
You've perhaps met these animals before. They are rather arty-farty. They don't realize that they aren't competing with Monet or Rembrandt but rather with Raju Choplanki who is desperately trying to revive his once killer brand.
They don't understand that they're not the artists they think they are, trying to prove how clever they are with ideas. They don't understand that they are actually another breed of sales men trying to prove, and prove over again that they have envious sales acumen. They don't understand that the only difference is that they do it with written words and pictures when a sales man uses the spoken word.
So what do they do?
They walk around the agency dazed. They talk to themselves when they're sure they have an audience. They go to the nearest Copywriter or Visualiser and tell them their idea sucks, with put-on genius. Or pontificates rather knowledgeably about the benefits of not writing a headline at all. Never mind that Arty-Farty can't come up with a line that has enough appeal. (A-F can only write A-F and expect lesser mortals to either get it or retire to Mars). Never mind again that A-F can't for the life of him write body copy because he believes that no one reads body copy.
You can spot these animals a mile away. Don't duck.
Or maybe you should duck and find your own corner. Unless you know of a better way to be rid of A-F's.
