Surgeon upset about cold sponge (8)
I believe the answer is:
scrounge
'sponge' is the definition.
(I've seen this before)
'surgeon upset about cold' is the wordplay.
'upset' indicates anagramming the letters.
'about' means one lot of letters goes inside another.
'cold' becomes 'c' (eg on taps).
'surgeon' is an anagram of 'srounge'.
'srounge' enclosing 'c' is 'SCROUNGE'.
(Other definitions for scrounge that I've seen before include "Seek something free from others" , "bum" , "Obtain (something) for free" , "Obtain by begging" , "Try to get hold of" .)
