Occasionally get daddy to twist (4)
I believe the answer is:
eddy
'twist' is the definition.
('eddy' can be a synonym of 'twist')
'occasionally get daddy' is the wordplay.
'occasionally' indicates alternate letters.
'get'+'daddy'='getdaddy'
The alternate letters of 'getdaddy' are 'EDDY'.
'to' acts as a link.
(Other definitions for eddy that I've seen before include "Rapid circular current" , "Circle around" , "Whirling current" , "making the rounds?" , "giddying effect" .)
