What does bumf mean?
Bumf is a chiefly British informal noun for worthless printed matter — the mass of forms, notices, leaflets, and official documents that accumulates in offices and letterboxes. It carries a dismissive, faintly comic connotation: nobody speaks fondly of 'the bumf', and saying it signals impatience with bureaucratic excess. The word originated as an abbreviation of 'bum-fodder', a 19th-century military slang term meaning paper fit only for use as toilet paper — a coarse joke that survives in the modern word's irreverent flavour. Today the lavatorial sense has faded, leaving the paperwork meaning dominant. Typical collocations include 'a pile of bumf' and 'wading through the bumf'. For writers, it offers a vividly British alternative to neutral terms like 'documentation' when a note of scorn is wanted, though its informality makes it unsuitable for formal prose.
nounPrinted matter of little value, especially official documents, forms, and other bureaucratic paperwork. An older, now rarer sense refers to toilet paper.

"The meeting was postponed because half the delegates were still wading through the bumf circulated beforehand."
"She sifted through the pile of bumf from the tax office looking for one relevant paragraph."
"The conference pack was mostly promotional bumf that went straight in the bin."
Bumf is normally used as an uncountable mass noun; a plural form 'bumfs' exists rarely but is best avoided.

It literally began life as 'bum-fodder' — paper deemed fit only for wiping your backside.

Etymology of bumf
Bumf derives from 'bum-fodder', a piece of late 19th-century military slang combining 'bum' (buttocks) with 'fodder' (food for livestock), describing paper worthless enough to serve as toilet paper. The term was clipped to 'bumf' in the early 20th century, and its sense shifted to cover any useless printed material, particularly bureaucratic documents. Its root 'bum' traces back further to Germanic origins, making 'bum' and compounds like 'bumboat' loose relatives rather than close cognates.
How bumf is actually used
Informal British usage, often carrying a mildly contemptuous tone toward bureaucracy. Rarely used outside the UK; American readers may not know it. The older lavatorial sense is largely obsolete but explains the word's origin.
