Five ejected from bar for suggestive look (4)
I believe the answer is:
leer
'suggestive look' is the definition.
(a sexually suggestive look)
'five ejected from bar' is the wordplay.
'five' becomes 'V' (Roman numeral).
'ejected from' suggests deleting specific letters.
'bar' becomes 'lever' (lever is a kind of bar).
'lever' with 'v' removed is 'LEER'.
'for' is the link.
(Other definitions for leer that I've seen before include "Give sly look" , "Stare suggestively" , "Look lecherously" , "Lascivious gaze" , "Gaze lasciviously at" .)
