Heavy kangaroo? (7)
I believe the answer is:
This could be a double definition.
'heavy' is the first definition.
(both can mean a member of security staff)
'kangaroo?' is the second definition.
Although both the answer and definition are singular nouns, I can't see how they can define each other.
Can you help me to learn more?
(Other definitions for bouncer that I've seen before include "Dud cheque" , "Chucker-out for nightclub" , "Club doorkeeper" , "One who keeps troublemakers out of a bar" , "A heavy - ball, say" .)
