Pillarian slip

From Memory Alpha, the free Star Trek reference.

A Pillarian slip is a word in the Denobulan language for inadvertently saying something that represents what they're thinking, but not what they want others to think they're thinking. The Human phrase for this is a "Freudian slip", categorized by Doctor Sigmund Freud.

In 2152, Doctor Phlox said that Captain Archer had used two pillarian slips in 30 seconds, so he probably had something on his mind. (ENT: "A Night in Sickbay")

This was named after executive producer Michael Piller. Base on the superficial similarity in naming, it might be possible "Pillar" was a Denobulan doctor, similar to Freud.
