What you might be doing shortly after dropping off party spirit (6)
I believe the answer is:
dozing
'what you might be doing shortly after dropping' is the definition.
I can't tell whether this defines the answer.
'party spirit' is the wordplay.
'party' becomes 'do' (do can informally mean a party).
'spirit' becomes 'zing' (I've seen this before).
'do'+'zing'='DOZING'
'off' acts as a link.
Can you help me to learn more?
(Other definitions for dozing that I've seen before include "Lightly asleep" , "Sleepy" , "Nodding off" , "Napping" .)
