buddyroo slang

The letters, reported the New York Times, are full of "regular-guy" comments from Salinger: he refers to his friend as "Buddyroo" and himself as "moron that I am".

In a voice which could be that of The Catcher in the Rye's central character, disaffected teenager Holden Caulfield, Salinger variously addresses Mitchell as "buddyroo", "old orange" and "old toot".
