Turn back before Leslie gives a dirty look (5)
I believe the answer is:
ogles
'gives a dirty look' is the definition.
I can't tell whether this defines the answer.
'turn back before leslie' is the wordplay.
'turn' becomes 'go' (a person's move in a board game).
'back' says the letters should be written in reverse.
'before' means one lot of letters go next to another.
'leslie' becomes 'les'.
'go' in reverse letter order is 'og'.
'og'+'les'='OGLES'
Can you help me to learn more?
(Other definitions for ogles that I've seen before include "Looks at amorously, makes eyes at" , "Looks longingly at" , "Leers" , "Casts amorous glances" , "Looks at (someone) lecherously" .)
