Noah's second son (3)
I believe the answer is:
ham
'noah's second son' is the definition.
(Ham was Noah's second son)
This is all the clue.
(Other definitions for ham that I've seen before include "Flamboyant actor, meaty type" , "Tasty meat for thespian who overacts" , "Poor person acting" , "Meat for excessive actor" , "Bad actor; Noah son" .)
