Possible swinger with a hangup! (3)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
bob
'possible' is the definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for bob that I've seen before include "line of verse" , "Hairstyle cut shortly and evenly all round" , "Set of changes" , "-- Dylan, singer" , "Old coin for Robert" .)
