Barbie greeting when out perhaps carrying daughter (4)
I believe the answer is:
gday
'barbie greeting' is the definition.
'gday' can be an answer for 'greeting' (I've seen this before). I'm unsure of the 'barbie' bit.
'out perhaps carrying daughter' is the wordplay.
'out perhaps' becomes 'gay' (I can't explain this - if you can you should give a lot more credence to this answer).
'carrying' indicates putting letters inside.
'daughter' becomes 'd' (genealogical abbreviation).
'gay' placed around 'd' is 'GDAY'.
'when' is the link.
Can you help me to learn more?
(Other definitions for gday that I've seen before include "welcome in Australia" , "Aussie opener" , "greeting from Adelaide?" .)
