Partly because I have a lousy vocabulary and partly because I act quite young for my age sometimes.
Though Holden is an unreliable narrator, he sometimes is correctly self aware: his vocabulary is indeed lousy. “Lousy” is also a word he uses quite repetitively, probably because he doesn’t know many synonyms.
Other words/phrases he uses a lot: goddam, quite, “and all,” phony, “if you want to know the truth,” “I really did/do,” hell, bastard, and anyway. (There are several others, too.)
