Not limited by social rules or feelings of self-consciousness; expressing oneself freely and openly.

Uninhibited → It is formed from "un-" (meaning not) and "inhibited" (from Latin "inhibere", meaning to hold back or restrain). The word "uninhibited" means not held back or restrained, allowing free expression.
Think of being 'not' ('un-') 'held back' ('inhibited') — that's why uninhibited means free to express oneself.
