Idiot called when first of messages missed, produced a tweet? (9)

I believe the answer is:

twittered

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

'produced a tweet?' is the definition.
Although both the answer and definition are past participle verbs, I don't understand how they can define each other.

'idiot called when first of messages missed' is the wordplay.
I cannot quite see how this works, but
'idiot' could be 'twit' (I've seen this in other clues) and 'twit' is found in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for twittered that I've seen before include "sang like a bird!" , "said nothing of value" , "Sounded like a small bird" , "Chirped away" .)
