Having popped off outside, everyone hung around (7)
I believe the answer is:
dallied
'hung around' is the definition.
(I've seen this in another clue)
'having popped off outside everyone' is the wordplay.
'having popped' means one lot of letters goes inside another.
'off outside' becomes 'died' (I can't justify this - if you can you should believe this answer much more).
'everyone' becomes 'all' (all people).
'died' going around 'all' is 'DALLIED'.
Can you help me to learn more?
(Other definitions for dallied that I've seen before include "Idled or flirted" , "moved slowly" , "Held back" , "Hung about" , "Dawdled or wasted time" .)
