God having party back at home (4)
I believe the answer is:
Here is my best explanation:
'god' is the definition.
(Odin is an example)
'party back at home' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'back' is a reversal indicator.
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'do' back-to-front is 'od'.
'having' acts as a link.
