Woman drops young hunk for being somewhat rowdy (7)
I believe the answer is:
laddish
'woman drops young hunk' is the definition.
I can't judge whether this defines the answer.
'being somewhat rowdy' is the wordplay.
'being' becomes 'lad' (lad is a kind of being).
'somewhat rowdy' becomes 'dish' (I can't explain this - if you can you should give a lot more credence to this answer).
'lad'+'dish'='LADDISH'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for laddish that I've seen before include "Like a young man" , "Boisterously macho" , "like a boisterous youngster" , "Macho and immature" , "Youthfully boisterous" .)
