See punk whirling in dance (5-2)
I believe the answer is:
knees-up
'dance' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'see punk whirling' is the wordplay.
'whirling' indicates anagramming the letters.
'see'+'punk'='seepunk'
'seepunk' with letters rearranged gives 'KNEES-UP'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for knees-up that I've seen before include "Informal party with dancing" , "Lively informal party" , "Dance with Mother Brown" , "Lively party (colloq.)" , "Riotous dance - party" .)
