oral personality

(psychology) An individual who is mouth-centered far beyond the age when the oral phase should have been passed, and who exhibits oral erotism and sadism in disguised and sublimated form.

According to the original theories of psychoanalysis, a personality fixed emotionally in the oral stage of development, whose sexual and aggressive drives are satisfied by putting things in his or her mouth. Depending on when the fixation occurs, oral personalities tend to be either optimistic, generous, and gregarious or aggressive, ambitious, and selfish. More recently, the term has come to refer to anyone who seeks pleasure through eating or sucking: “I didn't realize he was an oral personality until I saw him smoking and chewing gum at the same time.” (Compare anal personality.)

The noun has one meaning:

Meaning #1: (psychoanalysis) a personality characterized either by generous optimism or aggressive and ambitious selfishness; formed in early childhood by fixation during the oral stage of development
