Bunter being goatish? (5)
I believe the answer is:
billy
'bunter being' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for billy that I've seen before include "The familiar male goat" , "Goat; camper's kettle" , "Camper's pot" , "Metal camping can for tea" , "Light metal cooking pot used for camping" .)
