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

'call' is the definition.

I can't explain the remainder of the clue.

(Other definitions for moo that I've seen before include "Low (of cattle)" , "Cartoon sound of a cow" , "Irritating woman" , "Cow's low" , "Cow's call" .)

I've seen this clue in The Times.
