Butt of jokes seems too generic in part (6)
I believe the answer is:
stooge
'butt of jokes' is the definition.
(a stooge is the butt or victim of a joke)
'seems too generic in part' is the wordplay.
'in part' indicates a hidden word.
'STOOGE' is hidden in the letters of 'seems too generic'.
(Other definitions for stooge that I've seen before include "Fall guy" , "Butt of a comic's jokes" , "lackey" , "Yes-man" , "A comedian's assistant, butt of his jokes" .)
