psychopath

[skinem]

Had the distinct displeasure of meeting a true one this morning...

psy·cho·path

Pronunciation: 'sI-k&-"path
Function: noun
Etymology: International Scientific Vocabulary
: a mentally ill or unstable person; especially : a person affected with antisocial personality disorder

I doubt the etymology of this word originated with the International Scientific Vocabulary...they didn't just pull it out of thin air...
But, then again, maybe so.

most people I meet are either psychos or socios lately.

It all depends on which path you take.
