Hedonist not half like Mr Wooster around noon (9)

I believe the answer is:

libertine

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

'hedonist' is the definition.
(thesaurus)

'not half like mr wooster around noon' is the wordplay.
'not half' means to take half the letters.
'mr wooster' becomes 'bertie' (I can't justify this - if you can you should believe this answer much more).
'around' means one lot of letters goes inside another.
'noon' becomes 'n' (abbreviation for noon).
'like' halved is 'li'.
'bertie' going around 'n' is 'bertine'.
'li'+'bertine'='LIBERTINE'

Can you help me to learn more?

(Other definitions for libertine that I've seen before include "reprobate" , "Morally dissolute" , "Roue" , "Rou" , "of roues" .)
