'gluttony and lust?' is the definition.
I know that both 'gluttony' and 'lust' relate to this answer.

'omens not good after virulent' is the wordplay.
'omens' becomes 'signs' (I've seen this in another clue).
'not' suggests deleting specific letters.
'good' becomes 'g' (abbreviation).
'after' means one lot of letters go next to another.
'virulent' becomes 'deadly' (synonyms).
'signs' with 'g' taken out is 'sins'.
'sins' put after 'deadly' is 'DEADLY SINS'.
