I believe that may be the first time I've seen buggery used in a sentence before.....
Phil....your mate is using the term as profanity, yes?
for the rest of us, the definition of "buggery" is "sodomy"!
Old English is such a colorful language! 
heheh
more of a description next to nothing it means
I use it a lot when I speak also bugger, or buggered
I know what you mean by it

we have another saying for that ( can not post that here though )
but then I laugh every time I hear fanny back as we have another slang saying for fanny

and it ain't a on the rear
I should use more slang on here hehe
