Colossal idiots regularly taking sides to exchange words (6)

I believe the answer is:

lyrics

I'm a little stuck... Click here to teach me more about this clue!

'words' is the definition.
(I have seen 'Words of songs ' mean 'lyrics' so perhaps 'words' could also mean 'lyrics')

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for lyrics that I've seen before include "words in numbers" , "words to perform" , "Short song-like poems" , "Words used in songs" , "Words of a pop song" .)

I've seen this clue in the Sydney Morning Herald.
