American boy outside shouting where are hidden presents? (4,3)
I believe the answer is:
bran tub
'where are hidden presents?' is the definition.
(lucky dip with prizes hidden in bran)
'american boy outside shouting' is the wordplay.
'american boy' becomes 'bub' (US term of address for a boy or man).
'outside' means one lot of letters goes inside another.
'shouting' becomes 'rant'.
'bub' going around 'rant' is 'BRAN TUB'.
(Other definitions for bran tub that I've seen before include "Lucky-dip container" , "Container for lucky dip" , "Gifts from here" , "place for a dip" .)
