Inhibitions are certainly removed after a couple, things one would not normally say or do. Everyone has a mask to some degree and the hooch definitely removes it. I'd say that the effect amplifies certain aspects of one's mood at the time, which may or may not be a reflection of the person's nature as a whole, just a glimpse of something hidden.
I usually just write off things people say or do when drunk. Perceptions and emotions are skewed by the effect and are not usually how the person relates, unless of course it happens repeatedly in which case, I believe it's not so much the alcohol as it is a sign of something deeper.
That being said, I tend to become rather very extroverted and "flirty" when popped and can talk my way in or out of pretty much anything.
