Draw stomach back (3)
I believe the answer is:
tug
'draw' is the definition.
(tugging is a kind of drawing)
'stomach back' is the wordplay.
'stomach' becomes 'gut' (I've seen this before).
'back' says the letters should be written backwards.
'gut' back-to-front is 'TUG'.
(Other definitions for tug that I've seen before include "Pull at the towing vessel" , "Pull; loop on saddle" , "draw with some effort" , "Haul" , "Pull jerkily" .)
