'twice' is the definition.
(synonyms)

'pay out some subs' is the wordplay.
'pay' becomes 'dole' (I can't justify this - if you can you should believe this answer much more).
'out' indicates putting letters inside.
'some' means to look at the middle letters.
The middle letters of 'subs' are 'ub'.
'dole' enclosing 'ub' is 'DOUBLE'.
