sanctimony

I'm a little stuck... Click here to teach me more about this clue!

'affected piety' is the definition.
'sanctimony' can be an answer for 'piety' (thesaurus). I'm not certain of the 'affected' bit.

'upsetting a non-mystic' is the wordplay.
'upsetting' is an anagram indicator.
'a'+'non'+'mystic'='anonmystic'
'anonmystic' is an anagram of 'SANCTIMONY'.

Can you help me to learn more?

(Other definitions for sanctimony that I've seen before include "Pious hypocrisy" , "false piety!" , "Simulated holiness" .)
