Did she carry your cousins in the middle of the beauty centre? (4)
I believe the answer is:
aunt
'did she carry your cousins' is the definition.
(mother of your cousins)
'in the middle of the beauty centre?' is the wordplay.
'in the' is an insertion indicator.
'middle of' becomes 'au' (I can't explain this - if you can you should give a lot more credence to this answer).
'the' becomes 't' (the is pronounced as a 't' sound in some dialects).
'beauty' becomes 'stunner' (a stunning person).
'centre?' says to take the centre (I've seen 'centres' mean this).
The central letter of 'stunner' is 'n'.
'au'+'t'='aut'
'aut' placed around 'n' is 'AUNT'.
Can you help me to learn more?
(Other definitions for aunt that I've seen before include "Tuna gone bad for the relative" , "Female relative" , "Female relation" , "Charley's in play?" , "Sister of father/mother" .)
