Point to bad pig food (5)
I believe the answer is:
swill
'pig food' is the definition.
(I've seen this before)
'point to bad' is the wordplay.
'point' becomes 'SW' (SW is an example).
'to bad' becomes 'ill' (associated in meaning).
'sw'+'ill'='SWILL'
(Other definitions for swill that I've seen before include "drink heavily" , "Wet feed for pigs" , "Hogwash" , "Pigfeed" , "Wash" .)
