I have that. And it's painful to watch my own teenage moodiness and antics at times (painful to myself). I'm 35.
It's not exactly being like a 14 yo. It's rather like being 14 yo when it comes to emotions and 100 yo when it comes to logic and wisdom. it's not exactly general retardation. it's rather like being selectively ehem.. ret*d in some areas. Particularly social stuff. <- the definition of AS?

Possibly Aspie (diagnosed by an autism expert, doc moves abroad, forced to change docs and all say it's schizophrenia NOS or schizo-affective disorde or personality disorders. initial doc was a colleague of uncle Simon btw. you do the math.). (edit: by Uncle Simon I mean Simon Baron Cohen. Just to clear things up.)
