DA

Not a District Attorney - in this case, we are talking about a 1950s-style haircut in which the hair is tapered at the back, to resemble a duck's arse (hence DA).

Mark Kermode is as enamored of the DA as he is of everything else from that decade. He noticed that Indiana Jones And The Kingdom Of The Unmemorable Name Made Of Gold wasn't working when he became more interested in why Sleepy leBeef's DA looked like a wig than in the movie's actual plot.
