Womaniser (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
lothario
'womaniser' is the definition.
(I know that Lothario is a type of womaniser)
This is the entire clue.
(Other definitions for lothario that I've seen before include "Casanova" , "Successful womaniser" , "Seducer, rake" , "Heartbreaker" , "Libertine or woman-chaser" .)
