Freudian slips and malapropisms are different things, Red. The former are instances of mis-speaking which actually reveal some deeper frame of mind or suppressed desire. Example:"Honey, where are my Argyle sex?". A malapropism is a pretentious misuse of a word revealing ignorance, usually humorous, as '"Caparisons are odorous," she proclaims."' Or one by an eigth grader:

"We just learned about something new in health class, actually. I never heard of it before."

"Oh really? What was it?" I asked.

"We learned about girls who are anorexic and ballistic."

In this case you could argue that the use of ballistic for bulimic was possibly a malapropism AND a Freudian slip! :>)
