Furiously tail chap pinching old banger (9)
I believe the answer is:
chipolata
'banger' is the definition.
(I've seen this before)
'furiously tail chap pinching old' is the wordplay.
'furiously' indicates an anagram (the letters move around energetically or furiously).
'pinching' indicates putting letters inside (taking inside).
'old' becomes 'o' (common abbreviation eg in OE for Old English).
'tail'+'chap'='tailchap'
'tailchap' is an anagram of 'chiplata'.
'chiplata' placed around 'o' is 'CHIPOLATA'.
(Other definitions for chipolata that I've seen before include "Party snack" , "Type of sausage" , "Small thin sausage" , "banger" .)
