underminiac 

Noun. A word blend of undermine and maniac. Depicts someone who cannot help them self from making undermining comments. As with kleptomania the underminiac is largely unconscious of this behavior even though it might seem like they take sadistic gratification from it. Their victims are often left realizing how badly they were trashed for days and weeks afterward as many of the undermining comments are not initially obvious.

Lunch with that underminiac will leave your ego in a coma for weeks afterwards.

underliving 

A substandard way of living in which the individual may be unaware or is fooling himself into believing that he or she is living at the highest or correct level.

Underliving is usually a consequence of factors such as ignorance, mental blocks, emotional disturbances, trauma, a lack of imagination, the habit of underliving, having grown-up in a family and/or neighborhood where most people underlived, the lack of good examples and role models, and other foolish reasons such as fear of success.

Because different people have different goals and standards, what one individual may consider to be underliving, another individual may consider to be living correctly, thus well.

Overall, compared to Americans and people in other highly (materially) highly developed nations, approximately 90% of the people who live in developing nations can be said to be underliving. Some Americans also underlive.

I know it was lame to ditch to party to watch Sex and the City, but I needed some 'me' time. I knew I could trust you not to tell anybody; I'd never hear the end of it! Thanks for undermanding, bro.
