'expression of glee' is the definition.
I know nothing about this answer so I can't tell whether this works.

'nonsense passes' is the wordplay.
'nonsense' becomes 'jazz' (I've seen this in another clue).
'passes' becomes 'hands' ('hand' can be a synonym of 'pass').
'jazz'+'hands'='JAZZ HANDS'

'as' is the link.
