Stinking piece of chicken, maybe time for the bin? (4)
I believe the answer is:
high
'stinking' is the definition.
(thesaurus)
'piece of chicken maybe time for the bin?' is the wordplay.
'piece of chicken maybe' becomes 'thigh'.
'time' becomes 't'.
'for the bin?' suggests deleting specific letters.
'thigh' with 't' taken away is 'HIGH'.
(Other definitions for high that I've seen before include "American school" , "Great in rank" , "Tall, elevated" , "Euphoric; going off" , "Shrill" .)
