noun
prig
PRIG/prɪɡ/
A person who acts as though morally superior to others.

Etymology
The morally superior prig was first associated with theological scruples, then with an affected propriety that offended or bored others. Its origin is unknown; a connection with the earlier 'dandy' or 'thief' senses remains uncertain.
In context
