Stare rudely at (4)
I believe the answer is:
ogle
'stare rudely at' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ogle that I've seen before include "Eye lustfully" , "Cast flirtatious glances at" , "Regard lecherously" , "Lecherous look" , "Stare at in a lecherous manner" .)
