In my experience, "ambidextrous" means "equally adept with both hands" or at least signifies much less of the dominance of one hand over the other that you'd expect to find in a right- or left-handed person. While it's easy enough to see it also being used as a sly euphemism for "bisexual," I don't recall ever seeing "ambidextrous" used to mean deceitful, devious, dishonest, hypocritical or anything of that sort. I suspect that those more pejorative meanings haven't been in general English usage for three or four centuries.Lulz. Is it a common second meaning in English? It's absent in Italian.
Nonetheless, I did find sort of amusing the last sentence of this bit from the Wiki entry:
Wiki/Ambidexterity#Etymology said:The word "ambidextrous" is derived from the Latin roots ambi-, meaning "both", and dexter, meaning "right" or favourable. Thus, "ambidextrous" is literally "both right" or "both favourable". The term ambidexter in English was originally used in a legal sense of jurors who accepted bribes from both parties for their verdict.[2]
