Throw up after meat, so outwardly chaotic (9)
I believe the answer is:
shambolic
'chaotic' is the definition.
(I've seen this before)
'throw up after meat so outwardly' is the wordplay.
'throw up' becomes 'bol' (I am not sure about this - if you are sure you should believe this answer much more).
'after' says to put letters next to each other.
'meat' becomes 'ham' (ham is a kind of meat).
'so' becomes 'sic' ('so' in Latin).
'outwardly' indicates putting letters inside.
'bol' after 'ham' is 'hambol'.
'hambol' put inside 'sic' is 'SHAMBOLIC'.
Can you help me to learn more?
(Other definitions for shambolic that I've seen before include "Chaotic, mismanaged" , "all over the place?" , "Informally chaotic and disorganised" , "Chaotic and inefficient" , "all over the shop" .)
