What Tweeters do to have negative effect on originator? (4,4,2,5)
I believe the answer is:
come home to roost
'what tweeters' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'do to have negative effect on originator?' is the wordplay.
I cannot quite understand how this works, but
'do' could be 'come' ('come' can be a synonym of 'do') and 'come' is found within the answer.
'to' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for come home to roost that I've seen before include "have an effect on the originator" , "Tweeters do this" .)
