Overwhelmed by drink, team meeting journalist made a blunder (7,2)
I believe the answer is:
screwed up
'made a blunder' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
'overwhelmed by drink team meeting journalist' is the wordplay.
'overwhelmed by' means one lot of letters goes inside another.
'drink' becomes 'sup' (I've seen this before).
'team' becomes 'crew' (crew is a kind of team).
'meeting' means one lot of letters go next to another.
'journalist' becomes 'ed' (short for editor).
'crew'+'ed'='crewed'
'sup' going around 'crewed' is 'SCREWED UP'.
