Sort out parking in bad mood (5)
I believe the answer is:
strop
'bad mood' is the definition.
(I've seen this before)
'sort out parking' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'parking' becomes 'p'.
'sort' with letters rearranged gives 'stro'.
'stro'+'p'='STROP'
'in' is the link.
(Other definitions for strop that I've seen before include "Strip of leather on which razor is sharpened" , "Razor sharpener" , "temper tantrum" , "Bad temper - sharpen (a razor)" , "Prime cutthroat" .)
