Billiards bounce (5)
I believe the answer is:
carom
'billiards bounce' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for carom that I've seen before include "Glancing collision" , "Billiards shot" , "Form of billiards with no pockets" , "billiard shot" , "rebound" .)
