Bevvied Australian, dancing and making whoopee (10)
I believe the answer is:
saturnalia
'making whoopee' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'bevvied australian dancing' is the wordplay.
'australian' anagrams to 'SATURNALIA'.
Though, I'm not sure how the anagram is indicated.
'and' is the link.
Can you help me to learn more?
(Other definitions for saturnalia that I've seen before include "orgy" , "wild party" , "Ancient Roman December festival" , "Old festival" , "Wild Roman festival" .)
