Energetic man on board one pumped up for event (6,6)
I believe the answer is:
bouncy castle
'one pumped up for event' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'energetic man on board' is the wordplay.
'energetic' becomes 'bouncy' (I can't justify this - if you can you should believe this answer much more).
'man on board' becomes 'castle' (A castle is a piece in chess).
'bouncy'+'castle'='BOUNCY CASTLE'
Can you help me to learn more?
(Other definitions for bouncy castle that I've seen before include "Inflated fortress for kids" , "Inflatable fort for children's play" , "Blown-up fortress?" , "Inflatable device at fetes etc" , "[ENTERTAINMENT] loved by children" .)
