Sticky thing people eat maybe outside very loudly (6,5)
I believe the answer is:
toffee apple
'sticky thing' is the definition.
'people eat maybe outside very loudly' is the wordplay.
'maybe' indicates anagramming the letters.
'outside' is an insertion indicator.
'very loudly' becomes 'ff'.
'people'+'eat'='peopleeat'
'peopleeat' is an anagram of 'toeeapple'.
'toeeapple' enclosing 'ff' is 'TOFFEE-APPLE'.
(Other definitions for toffee apple that I've seen before include "Sticky fairground attraction?" , "Coated fruit on a stick" , "treat for kids" .)
