Drunkard present, whether you like it or not (2,5)
I believe the answer is:
so there
'whether you like it or not' is the definition.
(both can be said in defiance or stubbornness)
'drunkard present' is the wordplay.
'drunkard' becomes 'sot' (synonyms).
'present' becomes 'here' (both can mean in attendance).
'sot'+'here'='SO THERE'
(Other definitions for so there that I've seen before include "That will teach you!" , "message of defiance" , "Expression of triumph, derision, etc" , "I defy you" , "What are you going to do about that" .)
