'well' is the definition.
Both the answer and definition are adjectives.
Perhaps you can see a link between them that I don't see?

'pass close to celebrity and express disapproval' is the wordplay.
'pass' becomes 'ticket' (I've seen this before).
'close to' indicates one should take the final letters (the close of something is the end).
'and' says to put letters next to each other.
'express disapproval' becomes 'boo' (as in a crowd booing).
The final letter of 'celebrity' is 'y'.
'ticket'+'y'+'boo'='TICKETY-BOO'

Can you help me to learn more?

(Another definition for tickety-boo that I've seen is " Fine".)
