Corporation's year under pressure from drug ring (3-5)
I believe the answer is:
pot-belly
'corporation's' is the definition.
(corporation can humorously mean belly fat)
'year under pressure from drug ring' is the wordplay.
'year' becomes 'y'.
'under' is a charade indicator (letters next to each other) (in a down clue, some letters go below others).
'pressure from drug' becomes 'pot' (I am not sure about this - if you are sure you should believe this answer much more).
'ring' becomes 'bell' (both can mean to call on the phone).
'pot'+'bell'='potbell'
'y' after 'potbell' is 'POT-BELLY'.
Can you help me to learn more?
(Another definition for pot-belly that I've seen is " Protruding stomach".)
