We say he spilled rubbish (7)
I believe the answer is:
eyewash
'rubbish' is the definition.
(thesaurus)
'we say he spilled' is the wordplay.
'spilled' indicates anagramming the letters.
'we'+'say'+'he'='wesayhe'
'wesayhe' with letters rearranged gives 'EYEWASH'.
(Other definitions for eyewash that I've seen before include "Balderdash" , "Nonsense; cleansing lotion" , "Optic lotion - nonsense!" , "Optic solution to relieve irritation - rubbish!" , "Insincere talk or optical lotion" .)
