Paddy, dry, gulping an alcoholic drink (7)
I believe the answer is:
tantrum
'paddy' is the definition.
(thesaurus)
'dry gulping an alcoholic drink' is the wordplay.
'dry gulping an' becomes 'tant' (I can't explain this - if you can you should give a lot more credence to this answer).
'alcoholic drink' becomes 'rum' (I've seen this before).
'tant'+'rum'='TANTRUM'
Can you help me to learn more?
(Other definitions for tantrum that I've seen before include "Burst of temper" , "Child's outburst of bad temper" , "Childish outbreak of temper" , "Childish display of temper" , "Fit - pet" .)
