Catcher in the Rye- Metonymy

The Catcher in the Rye
by J.D. Salinger
pgs 53-105

Holden decides to go to a club, called the Lavender room, in the hotel he's staying at.  He wants to dance and decides to go over to a table of three women.  In describing and referencing them, Holden uses metonymy and other kinds of insulting names and descriptions.  When he first mentions them, he says, "I started giving the three witches at the next table the eye again. That is, the blonde one. The other two were strictly from hunger" (Salinger, 70).  Then he says, "Finally the blonde one got up to dance with me...the other two grools nearly had hysterics when we did" (70).  Later he said, "The other ugly one, Laverne, thought she was a very witty type" (Salinger, 75).
Holden rarely ever calls the women by their names.  He calls them "blonde one" and "ugly one."  This distances the women from Holden and the reader.  It demonstrates how judgment and simple-minded Holden is.  He judges many people solely by their outward appearance.  He calls people moron, stupid, ugly, etc.   This ties back to his insecurities.
Holden is characterized by his demeaning actions and words because the reader can see that Holden is judgmental, crude, and insecure.
