ogle

I'm a little stuck... Click here to teach me more about this clue!

'look' is the definition.
(ogling is a kind of looking)

I don't understand how the rest of the clue works.

(Other definitions for ogle that I've seen before include "Stare lewdly" , "Cast amorous glances" , "Gape at" , "Amorous stare" , "Amorous glance" .)

I've seen this clue in the Evening Standard.
