"plunging it back in a not unworrying manner, if one were a Freudian."

The Austrian neurologist and founder of pyschoanalysis, Sigmund Freud, believed that actions could be analysed and interpreted to reveal what was taking place in the unconscious mind, where unacceptable or uncomfortable thoughts might dwell.

If one were a Freudian, one might see this action as an accidental manifestation of a repressed sexual or hostile desire.
