Uuum a bit weird this, but when you think about it it makes sense; Guff is a term in England/Britain for passing wind [farting]. With the breathing methane thing, could this be a little joke? Classius 21:59, August 13, 2010 (UTC)

Yes, it could, put in the trivia that guff is slang for ...uh... flactulance, or some other more politically correct term. LOL. Sign your posts please. Que Sera, Sera 21:36, August 9, 2010 (UTC)

I added the trivia. Do i need to give a reference? The only one i could find that had the relevent British meaning isn't very family friendly. I just remember it as something we used to say at school a fair bit...usually after beans at lunch!! Classius 21:59, August 13, 2010 (UTC)
