derided

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

'mocked' is the definition.
(deriding is a kind of mocking)

'fast eddie about the queen' is the wordplay.
'fast' becomes 'did' (I can't justify this - if you can you should believe this answer much more).
'eddie' becomes 'ed'.
'about' indicates putting letters inside.
'the queen' becomes 'ER' (Elizabeth Regina).
'did'+'ed'='dided'
'dided' placed around 'er' is 'DERIDED'.

Can you help me to learn more?
