Tramp following superfluous documents (4)
I believe the answer is:
bumf
'superfluous documents' is the definition.
'bumf' can be an answer for 'documents' (I have seen 'Official documents ' mean 'bumf' so perhaps 'documents' could also mean 'bumf'). I am unsure of the 'superfluous' bit.
'tramp following' is the wordplay.
'tramp' becomes 'bum' (both can mean a homeless person).
'following' becomes 'f' (used when citing page numbers etc).
'bum'+'f'='BUMF'
Can you help me to learn more?
(Other definitions for bumf that I've seen before include "Junk-mail" , "official papers?" , "Boring documents etc" , "Official documents" , "pile of leaves" .)
