That’s greek for “socially ill”. It’s not really a widely recognised psychological construct, psychologists don’t really believe in it. But if I were to actually define it for the sake of argument, I’d say it describes disorders that impair social interaction and one’s ability to fit in in society. Like autism, or STPD, or clinical lycanthropy.

Again, not the same as being a dickhead. Psychologists aren’t interested in judging your morality, that’s priests.
