Total fool playing lotto with epidemic (8,5)

I believe the answer is:

complete idiot

'total fool' is the definition.

'playing lotto with epidemic' is the wordplay.
'playing' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'lotto' after 'epidemic' is 'epidemiclotto'.
'epidemiclotto' with letters rearranged gives 'COMPLETE IDIOT'.

I've seen this clue in The Guardian.
