Oliver —; dance (5)
I believe the answer is:
twist
I believe this is a double definition.
'oliver' is the first definition.
(I've seen this before)
'dance' is the second definition.
(I know this)
(Other definitions for twist that I've seen before include "Rotate rapidly" , "Turn into a distorted shape" , "Unexpected event" , "Intertwine, contort" , "dance from the 60s" .)
