Snap, crackle, and pop (6)
I believe the answer is:
noises
'snap crackle and pop' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for noises that I've seen before include "Disturbing sounds" , "Sounds, rackets" , "sounds unpleasant" , "Conventional phrases" , "Noses I turn up to sounds" .)
