Large parts I flipping look at lustily (4)
I believe the answer is:
ogle
'look at lustily' is the definition.
I can't tell whether this defines the answer.
'large parts i flipping' is the wordplay.
'large' becomes 'l'.
'parts' is an insertion indicator (in the sense of cuts or separates).
'i' becomes 'ego' (I've seen this before**).
'flipping' is a reversal indicator.
'l' placed within 'ego' is 'elgo'.
'elgo' backwards is 'OGLE'.
Can you help me to learn more?
(Other definitions for ogle that I've seen before include "Stare at lecherously" , "Look flirtatiously at" , "Eye flirtatiously" , "Eye greedily" , "Stare at in a lecherous manner" .)
