Pretend son’s out, getting meat (3)
I believe the answer is:
ham
'meat' is the definition.
(ham is a kind of meat)
'pretend son's out' is the wordplay.
'pretend' becomes 'sham' ('sham' can be a synonym of 'pretend').
'out' is a deletion indicator.
'sham' with 's' taken away is 'HAM'.
'getting' is the link.
(Other definitions for ham that I've seen before include "Succulent meat or extravagant actor" , "Overacting pig?" , "One of Noah's sons" , "Bad actor; Noah son" , "Licensed amateur radio operator" .)
