Hit feature gets cheers (4-4)
I believe the answer is:
chin-chin
'cheers' is the definition.
(I've seen this before)
'hit feature' is the wordplay.
'hit' becomes 'chin' (informal term meaning to punch someone's chin).
'feature' becomes 'chin' (facial feature).
'chin'+'chin'='CHIN-CHIN'
'gets' is the link.
(Other definitions for chin-chin that I've seen before include "Cheers, bottoms up" , "good health ..." , "Down the hatch!" .)
