Long digital film dealt unusually with gender ID (6,6)
I believe the answer is:
middle finger
'long digital' is the definition.
(digital can mean a finger)
'film dealt unusually with gender id' is the wordplay.
'dealt unusually with' indicates an anagram.
'gender'+'id'='genderid'
'film' anagrammed with 'genderid' makes 'MIDDLE FINGER'.
(Other definitions for middle finger that I've seen before include "Longest digit" , "Central digit" .)
