Paint rude scene including butts in (8)
I believe the answer is:
intrudes
'butts in' is the definition.
(I've seen this in another clue)
'paint rude scene including' is the wordplay.
'including' indicates a hidden word.
'INTRUDES' is hidden in the letters of 'paint rude scene'.
(Other definitions for intrudes that I've seen before include "Enters uninvited and unwelcome" , "Imposes without welcome" , "Interferes" , "Comes or joins in without being wanted" .)
