'routine' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'star getting caned terribly' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'getting' is a charade indicator (letters next to each other).
'terribly' indicates anagramming the letters.
'caned' with letters rearranged gives 'dance'.
'sun'+'dance'='SUN DANCE'

Can you help me to learn more?

(Other definitions for sun dance that I've seen before include "Kid associated with Butch Cassidy" , "Native American ceremony" , "Butch Cassidy and the ... Kid (film)" .)
