Bin containing hot buffet (6)
I believe the answer is:
thrash
'buffet' is the definition.
(thesaurus)
'bin containing hot' is the wordplay.
'bin' becomes 'trash' (both can mean to dispose of something).
'containing' indicates putting letters inside.
'hot' becomes 'h' (abbreviation eg on taps).
'trash' placed around 'h' is 'THRASH'.
(Other definitions for thrash that I've seen before include "Trounce, beat soundly" , "Beat hard" , "Beat up, batter" , "Whip repeatedly" , "Wallop" .)
