I am having trouble finding a particular quote for The Catcher in the Rye.I know that the quote talks about about people sticking to the chess club...

I think that the quote of which you speak is located in
Chapter 17.  Holden is giving his opinion about the very nature of phoniness that exists
at a Boys' school, and in the process reflects how he, himself, does not belong
anywhere.  It is a quote that is reflective of many elements.  The first is that Holden
has a very distinct view of the social setting of school, and adolescence, in general. 
Defining socialization through the deliberate use of the word "clique," Holden defines
the process by which people socialize as one of division.  In "everyone sticking
together," Holden also brings out how there is little in way of social diversity and
interaction.  Holden brings out how there is only separate monologues, and not true
dialogue.  At the same time, there is a bit of longing in his assessment because as he
criticizes everyone "sticking together" with their own clique, there does not seem to be
any domain that includes him.  There is a note of bitterness in this light, bringing out
the complex relationship Holden possesses towards how social constructions are both made
and his association with them.
