Son of Marge and Homer (4)
I believe the answer is:
matt
'son of marge and homer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for matt that I've seen before include "- Lucas (Little Britain)" , "Telegraph cartoonist" , "Lacking a shine" , "Not glossy" , "Dull, not shiny" .)
