Top bouncer (6)
I believe the answer is:
jumper
This might be a double definition.
'top' is the first definition.
(type of garment worn as a top)
'bouncer' is the second definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for jumper that I've seen before include "Garment for upper body, or an athletic leaper" , "Woolly" , "Top" , "Sweater" , "that may be long for an athlete" .)
