Looking and prising five out (7)
I believe the answer is:
leering
'looking' is the definition.
(leering is a kind of looking)
'prising five out' is the wordplay.
'prising' becomes 'levering' ('lever' can be a synonym of 'prise').
'five' becomes 'V' (Roman numeral).
'out' indicates named letters should be taken away.
'levering' with 'v' removed is 'LEERING'.
'and' acts as a link.
(Other definitions for leering that I've seen before include "giving the glad eye" , "Gazing lasciviously" , "Looking suggestively" , "Ogling" , "appearing lascivious" .)
