Crossword Genius

Drops perhaps after this ritual exercise (4,5)

Ross

I believe the answer is:

rain dance

This clue could be a double definition.

'drops perhaps after this' is the first definition.
(as in rain drops)

'ritual exercise' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps you can see an association between them that I don't see?

I've seen this clue in The Times.
