Take that lush present (2,5)
I believe the answer is:
so there
'take that' is the definition.
(both phrases are said to show defiance)
'lush present' is the wordplay.
'lush' becomes 'sot' (both can mean a drunk).
'present' becomes 'here' (both can mean in attendance).
'sot'+'here'='SO THERE'
(Other definitions for so there that I've seen before include "Derisive expression" , "defiant expression" , "Defiant remark" , "Triumphant put-down" , "message of defiance" .)
