OK - I guess I started this, so let me clarify this piece of (British) slang, commonly used in Australia and New Zealand.
Bugger has many meanings - let me count the ways.
Bugger! Expression of annoyance - damn! (having dropped and broken your last bottle of '82 Latour) Bugger (up) To damage or destroy (He missed the change and buggered the gearbox - or "That bugger Bill Spohn left the wine behind and buggered up our weekend!) Bugger Off! Go Away! Piss Off! (Not quite as offensive as F**k off!) Bugger All Very small quantity. (There was bugger all left in that bottle by the time I finished) Bugger About Waste time (He buggered about all day trying to fix that gearbox!) Bugger (Term of playfull respect) He is a good bugger; that old bugger is a hard worker!) Bugger One who is difficult or awkward (He is a hard bugger to work for!) Bugger the act of anal sex Bugger Me! Expression of surprise or amazement (Hey, you just won the lottery - well bugger me!!!) Buggered Very tired (I've been working all day, and I'm absolutley buggered!)
So, you can see, noun, verb and much more.
Here endeth this lesson - It's 11:30pm - it has been a long day and I'm buggered, so I think that I shall bugger off to bed!
