Freud

I'm think I found an interesting link between Freud's theory and swear words.

Oral stage (exemplified by an infant's pleasure in nursing), then in the anal stage (exemplified by a toddler's pleasure in evacuating his or her bowels), then in the phallic stage. Freud argued that children then passed through a stage in which they fixated on the mother as a sexual object (known as the Oedipus Complex) but that the child eventually overcame and repressed this desire because of its taboo nature. The repressive or dormant latency stage of psychosexual development preceded the sexually mature genital stage of psychosexual development.
