Engages in revelling or resist awkwardly? (8)

I believe the answer is:

roisters

I'm a little stuck... Click here to teach me more about this clue!

'engages in revelling' is the definition.
I can't tell whether this defines the answer.

'or resist awkwardly?' is the wordplay.
'awkwardly?' indicates an anagram (I've seen 'awkwardly' mean this).
'or'+'resist'='orresist'
'orresist' with letters rearranged gives 'ROISTERS'.

Can you help me to learn more?

(Other definitions for roisters that I've seen before include "Noisily celebrates" , "Parties" , "[WASSAILS]" , "Makes merry in sorriest way" , "Carouses" .)

I've seen this clue in the Sydney Morning Herald.
