Drunkard now offering defiant expression (2,5)

I believe the answer is:

so there

'defiant expression' is the definition.
(I've seen this before)

'drunkard now' is the wordplay.
'drunkard' becomes 'sot' (synonyms).
'now' becomes 'here' (I've seen this in other clues).
'sot'+'here'='SO THERE'

'offering' acts as a link.

(Other definitions for so there that I've seen before include "I defy you" , "message of defiance" , "Expression of defiance" , "Expression of triumph, derision, etc" , "Triumphant put-down" .)

I've seen this clue in The Everyman puzzle in The Observer.
